Okay, we have tons of algebra programs that can work with numbers but do not have any help with Story problems.
Can anyone tell us the formula for solving this, step by step.
Nine pounds of Sweet Potatoes cost the same as Six pounds of Apples. One pound of Sweet Potatoes cost twice as much as one pound of Onions. While a pound of Apples costs 24 cents more than a pound of Onions.
(we can't solve it with NO integers)
Can anyone tell us how to do this?
Jen,
Why is it that if the sentence says..
One pound of Sweet Potatoes cost twice as much as one pound of onions.
Why isn’t it
2S=O
?
I just know that somewhere amongst those numbers there is a racist code.
Here’s what you do next time. Just ask Null and Void. Nully knows everything.
I helped you with your English and Grammar. Now go to Math.com for your algebra assistance.

Hey if this were the DU site, there would be the following kinds of answers:
(1) 3.
(2) "How dare this teacher want specific answers!!!"
(3) Complaints about the high price of apples and demand for government price controls.
(4) "How do they expect us to do math when we can't read the problem?"
Welcome to Free Republic!
You will find many challenges here. And if you have watched what our government has been doing then you know that a normal calculator doesn’t have enough digits.
The problem with any of the internet sites is that they will let you plug in numbers but won’t solve text problems.
All numbers contain racist code because liberals say blacks can’t do math.
Because one pound of sweet potatoes are equal in price to two pounds of onions. Therefore 1S=2O
Really?
Here’s another Math problem (an oldie but goodie).
Teaching Math in 1950:
A logger sells a truckload of lumber for $100.
His cost of production is 4/5 of the price.
What is his profit?
Teaching Math in 1960:
A logger sells a truckload of lumber for $100.
His cost of production is 4/5 of the price, or $80.
What is his profit?
Teaching Math in 1970:
A logger exchanges a set “L” of lumber for a set “M” of money. The cardinality of set “M” is 100. Each element is worth one dollar. Make 100 dots representing the elements of the set “M.” The set “C”, the cost of production contains 20 fewer points than set “M” Represent the set “C” as a subset of set “M” and answer the following question:
What is the cardinality of the set “P” of profits?
Teaching Math in 1980:
A logger sells a truckload of lumber for $100.
His cost of production is $80 and his profit is $20.
Your assignment: Underline the number 20.
Teaching Math in 1990:
By cutting down beautiful forest trees, the logger makes $20.
What do you think of this way of making a living?
Topic for class participation after answering the question:
How did the forest birds and squirrels feel as the logger cut down the trees?
There are no wrong answers.
Teaching Math in 2000:
A logger sells a truckload of lumber for $100.
His cost of production is $120.
Show how Arthur Andersen determines that his profit margin is $60?
Teaching Math in 2020:
A logger sells a truckload of artificial lumber for $1000
His cost of recycling trash is $100
Show the effect a barren earth has on profit margin.
Teaching Math in 3000:
A..................?
I’d listen to him. He’s Alway’s Right.
That is the clearest solution so far for me.
LOL!
It’s Switched on Schoolhouse, a Christian Curriculum.
Next. GUESS AN FALSE ANSWER.
Set any ONE of the prices.
For example, set the price of an apple = $1/lb.
Then solve the equations.
By Equation 1, the cost of sweet potatoes for the false solution is $0.67.
and by Equation 2, the cost of Onions is $0.33/lb
and by Equation 3, the price of of a lb of apples is $0.33/lb MORE than a lb of onions. So this equation does not solve. It should only be $0.24/lb MORE than a lb of onions.
THIS MEANS OUR INITIAL GUESS IS TOO HIGH.
So lower the initial guess and resolve the equations until the final equation is solved correctly.
Eventually you will get to..
So apples cost $0.72/lb; sweet potatoes cost $0.48/lb and Onions cost $0.24/lb.

Mine doesn't do negative trillions.
