Abraham has visited 10 states already. He has a goal of visiting all 50 states. He plans to achieve this goal by visiting 5 new states per year (y) for the next several years. Which equation and solution shows the number of years that it will take for Abraham to meet his goal?
A
5y+10=50; y=12 years

B
10y+5=50; y=5.5 years

C
5y+10=50; y=8 years

D
10y+5=50; y=4.5 years

C

Step-by-step explanation:

5 states per year = 5y

Already visited 10 states = +10

5y + 10 = 50

To find y

5y = 50 - 10

5y = 40

y = 40/5

y = 8 years
