Problema Solution
Mrs. Brown’s Girl Scout
troop had a car wash to earn
some funds. They saved
16
of
the money. They used
12
of the
remaining money to go horseback
riding. They then had
$100.00 left. How much did they
initially make washing cars?
Answer provided by our tutors
We assumed 'saved 16' to mean 'saved $16.00' and we also assume 'used 12' to mean 'used $12.00'.
The total amount initially made is $100 plus the amounts saved and spent on horseback riding. We also assume that the $16 saved is not a part of the $100.00 left over (even though that money has not been spent... presumably it was set aside in a special fund).
Based on these assumptions, the initial amount would be:
100+16+12=128
so the initial amount made washing cars would appear to have been $128.00
