Question

Imani has 2 part-time jobs. One pays $7.50 per hour for dog grooming, and the other pays $8.25 per hour at a grocery store. Help her find a way to earn (exactly) $500.

Answer 1

Answer:

‘d’ represents dog grooming
‘g’ represents grocery store

7.50d+8.25g ≤ 500


All money has to be exactly equal to $500, or less than.

Answer 2

To solve this problem, we can simply write out an equation to represent the problem and then solve for the unknown variable. Imani needs to work a cumulative sum of 31.75 hours in her two jobs in order to earn $500.

What is an Equation?

This is a mathematical expression used to represent word problems.

Data;

• dog grooming = 7.50
• grocery store = 8.25

One easy and fast method to do this is to determine how many hours she needs to work to earn exactly $500 from both jobs.

$7.50x + 8.25x = 500\\15.75x = 500\\x = \frac{500}{15.75} \\x = 31.75$

Imani needs to work a cumulative sum of 31.75 hours in her two jobs in order to earn $500.
