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

Charlie reads quickly. He reads 1 3/7 pages every 2/3 minutes. Charlie reads at a constant rate
svp [43]
True, he reads at a constant rate because he reads 10/7 pages every 2/3 minutes... 
2/3 of a minute is 40 seconds... let's use that
(10/7) / 40 = x / 60
600/7 = 40x
divide both sides by 40
15/7 = x
2 1/7 pages per minute

Hope this helps :)
