Question

Joe and maggie are working at Mcdonalds. Joe makes $8.50 per hour while Maggie makes $9.00 per hour. How much will they both make altogther if they work x number of hours

Answer 1

8.5x + 9x = y

That is because you don't know how many hours they worked, so you can't how much money they made.

If you plugged in 4 hours for the x's you'll do something like this:

8.5 (4) + 9 (4) = y

34 + 36 = y

70 = y

That is how you would do it if you have the number of hours they worked.

Answer 2

m = 8.50 x + 9x

Explanation:

Hi, to solve this we have to write an expression where:

x : hours worked

m : money earned by Joe and Maggie

Joe makes $8.50 per hour, so if he works x hours he earns $8.50 (x) .

Maggie makes $9 per hour, so if she works x hours she earns $9 (x) .

If they work x number of hours, they both will make:

m = 8.50 x+ 9x
