1. Question:

Sarah sells fruit trays at a salad shop. Last week, she sold 450 fruit trays for \$8 per tray. In previous weeks, she found that for every \$0.85 increase in the price, she sold 15 fewer fruit trays. Which equation can be used to find Sarah’s weekly sales income in dollars, y, after x price increases of \$0.85?

The equation used to find Sarah’s weekly sales income is:

Solution:

Let “y” be the sarah income

From given,

Sarah’s income = Number of trays x Rate per tray

Last week, she sold 450 fruit trays for \$8 per tray

Therefore,

y = 450 x 8

In previous weeks, she found that for every \$0.85 increase in the price, she sold 15 fewer fruit trays

If there is an increase of 0.85 in price,

New price = 8 + 0.85

For x number of increases,

new price = 8 + 0.85x

She sold 15 fewer fruit trays

Number of trays reduced = 450 – 15x

Thus, Sarah’s income is:

Thus the equation used to find Sarah’s weekly sales income is found
