Take the total cost and subtract the registration fee.
56.25-12.5=$43.75
The remainder is what was spent on swim classes so divide by the cost of the swim classes.
$43.75/8.75=5 swim classes
The number of apples is x, and the number of oranges is y.
"Mia needs to bring at least 25 pieces of fruit to the school picnic."
means that x+y≥25
"She was told to be sure to bring more than 10 apples."
means that x≥10
thus, the inequalities are:
i) x+y≥25
ii) x≥10
Part A would be the second option, as well as part B
The answer is 3.375. Hope this helps. :D
