$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?
ОА.
y = -12.75.2 + 482.51 + 3,600
ОВ.
y = -12.7502 + 262.5+ 3,600
Ос. y =
-12.75.12 + 502.5.1 + 3,600
OD. y = -12.752 + 272.5x + 3,600
