Question

Elmo has two different part tike jobs and he works 20 hours per week at each job. He earns $8 per hour at one job. Which expression represents how much Elmo earned last week if he earns d dollars per hour at his other job?

Answer 1

Answer:

Earned = 160 + 20d

Step-by-step explanation:

Seeing as Elmo works 20 hours per week at each job, that means he worked 20 hours at the $8 job and 20 hours at the $d job.

First find how much he earned from his $8/hr job.

(20)8 = 160

Elmo earned $160 at this $8/hr job.

Next, we know he earns $d/hr at his other job, and he works 20 hours at that job as well.

(20)d = 20d

Add the earnings from both jobs together.

160 + 20d = total earnings
