The director of a summer day camp estimates that 120 children will join if the camp fee is $250, but for each $25 decrease in the fee, five more children will enroll.
Determine the linear equation that will represent the number of children who will enroll at a given fee. Hint: To write the slope, you need two points on the line. Show all work to receive full credit.
let x - the fee, y(x) - the number of children with this fee x.
We have y(250) = 120. We have also dy (change in y)=5 if dx (change in ...
A linear equation is written from a word problem.
