Adelyn Mcmahon · Answer 1

Sarah's income = Number of trays * Rate per tray

y = 450 * 8

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.

Number of trays reduced = 450 - 15x.

So, Sarah's income in this case is y = (450 - 15x) (8 + 0.85x).
