Chapter 6, Problem 9STP

To determine

To find: the maximum number of toppings A and her sister can get on theirpizza.

Answer to Problem 9STP

The maximum number of toppings is 4

Explanation of Solution

Given:

A and her sister spent $15

A medium pizza costs $11.50 plus $0.75 per topping

Calculation:

Assume the number of topping is: $x$

The equation will be:

  $11.50+0.75x<15$

From the above inequality we get:

  $11.50+0.75x<15$

  $11.50+0.75x-11.50<15-11.50$

  $\frac{0.75x}{0.75}<\frac{3.50}{0.75}[\text{ Divide both sides by }0.75]$

  $x<4.67$

Hence, the maximum number of toppings is:4

Conclusion:

Hence, the maximum number of toppings is:4
