The equation that best relates their revenue, y, to the number of items they sell, x, is:
y = -0.2x² + 15x
A business wants to model its income as a function of the number of items that it produces and sells. Because the business must decrease the price in order to sell more items, the relationship is not linear. Its income for selling various numbers of items is given by the table below.
# items (thousands)
revenue (thousands of dollars)
10
130
20
220
30
270
40
280
50
250
Which equation best relates their revenue, y, to the number of items they sell, x?
Oy = -0.2x² + 15x
y=139.56.1.02
y=-0.2x + 15
Oy 1.02x + 139.56
Oy = 15x20.2x
