Answer :
Answer:
- A. 3 weeks, $160
Step-by-step explanation:
If the value of y is same for both then we have equal right sides of equations
- 50x + 10 = 30x + 70
Solve this for x
- 50x - 30x = 70 - 10
- 20x = 60
- x = 60/20
- x = 3
Find the value of y
- y = 50*3 + 10 = 150 + 10 = 160
Correct choice is A
