Question

You are helping your neighbor prepare to move into their own place when they start college. Your neighbor is in charge of buying items for the kitchen. You find a microwave on sale for $79.99, a set of pots and pans for $59.99 and plates on sale for $2.25 each. Your neighbor only has $160 to spend. Write an inequality to represent the number of plates you can buy in terms of the microwave, pots and pans and the total amount. ​

Answer 1

the number of plates that can be bought is less than or equal to 8 (rounded down to a whole number since you cannot buy a fraction of a plate).

Explanation:

The inequality can be written as:

2.25x ≤ 160 - (79.99 + 59.99)

Simplifying this inequality:

2.25x ≤ 160 - 139.98

2.25x ≤ 20.02

Dividing both sides of the inequality by 2.25:

x ≤ 20.02 / 2.25

x ≤ 8.896
