Question

Rosa and her brother worked landscaping jobs last summer. Rosa earned $8 more than twice the amount earned by her brother. If their earnings totalled $71, how much did Rosa earn? NEED AN ANSWER

Answer 1

Rosa earned $50

Step-by-step explanation:

Two people Rosa & her brother
Her brother earns X
While Rosa earns 2X + 8
Now we gotta solve for X

They made $71. $71 minus X should give you Rosa’s pay

71 - X = 8 + 2X (subtract 8 from 71)
63 - X = 2X (add X to 2X)
63 = 3X (divide by 3)
21 = X

Plug in $21 for Rosa:
8 + 2(21)
8 + 42 = $50
