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?

Answer 1

The equation y = (450 - 15x)(8 + 0.85x) can be used to find Sarah's weekly sales income in dollars, y, after x price increases of $0.85.

Step-by-step explanation:

The equation that can be used to find Sarah's weekly sales income in dollars, y, after x price increases of $0.85 is:

y = (450 - 15x)(8 + 0.85x)

In this equation, x represents the number of price increases of $0.85, and y represents Sarah's weekly sales income. The equation takes into account the decrease in the number of fruit trays sold for every $0.85 increase in the price.

Answer 2

y=-12.75x^2+262.5x+3,600
