Rosa earned $50
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

Answer:
Correct option is c.
Step-by-step explanation:
The information provided is:
- It costs $83 a day to rent a car plus a required fee for insurance.
- The total cost for renting the car for 7 days is $621.
Then the cost of renting the car for 7 days will be, (83 × 7).
Let <em>b</em> denote the required fee for insurance.
Then the equation representing the total cost of renting is:
621 = 83(7) + b
Compute the value of <em>b</em> as follows:
621 = 83(7) + b
621 = 581 + b
b = 40
So, the correct option is c.
