Question

Anna earns $60 plus $2.50 for each table she cleans. Write and solve an inequality to find how many tables she must clean to earn at least $150 *

Answer 1

Answer:

60 + 2.5n ≥ 150

2.5n ≥ 90

n ≥ 36  She must clean 90 tables to earn at least $150.

Step-by-step explanation:

She earns $2.50 for each table she cleans so n represents the number of tables she cleans. You add that to $60. At least must mean that the inequality has to be equal to or bigger than 60 + 2.5n.

Now we just have to solve, which I do for you above in the 'Answer' section.

I hope this helps you!! ^-^
