Question

A used car dealer prices her cars so that she makes a minimum profit of 15% on each car sold. If she acquired a car for $4,500, which inequality can be used to determine the acceptable selling prices, p, of that car? 1.15 p less-than-or-equal-to 4,500 1.15 p greater-than-or-equal-to 4,500 p less-than-or-equal-to 1.15 (4,500) p greater-than-or-equal-to 1.15 (4,500)

Answer 1

D

Explanation:

Answer 2

`p\geq 1.15(4,500)`

Explanation:

If she makes a minimum profit, we need to use the symbol
`\geq`, which indicates minimum quality.

Let's call
`p` profit, so the inequality which represent this problem would be

`p\geq 1.15(4,500)`

The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.

Therefore, the right answer is the last choice.
