I got the $7.50 easy but that isn’t the correct answer.

Once you've gotten the $7.50, two of the three wrong answers can easily be eliminated: 50 dimes is $5 and 90 pennies is $0.90. Dividing the 30 quarters by 2 and then by 2 again would quickly confirm that one as the correct answer.

I do agree with earlier posts, though, that pressure was probably a huge factor in her difficulties.

I went the route

1 Euro = $1.50

5 Euros = $7.50

1 Quarter = $0.25

$7.50/0.25 = 30

Answer = A

If you can get to 7.50 then 25 (25 cents) goes into 75 3 times add the zero to get 30 quarters.
