Problem of the Week
Problem D
Let's Dance

The student council at POTW High School is throwing a school dance. They want to give a welcome gift to each Grade \(9\) student that attends the dance.

Gifts-R-Us charges \(\$1.00\) per gift. However, if they were to purchase the gifts at Gifts-R-Us, they would exceed their budget by \(\$17\).

At Presents-4-U, they only charge \(\$0.80\) per gift. At this price, the student council would have \(\$5.00\) left over in their budget.

Determine the number of gifts the student council is planning to buy.
