Question

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?

Answer 1

10 + 5y = 50, y = 8 (years)

Explanation:

5y - states. that Abraham still plans to visit.

10 + 5y = 50

5y = 50 - 10

5y = 40

y = 8

Answer 2

Answer: 10+5y=50; y=8 years

Explanation:

Since Abraham has already visited 10 states, and he wants to visit 5 states per year, we get the equation 10+5y=50. The 10 is the number is states he has already visited. 5y represents the rate at which he visits the remaining states. 50 is the total amount of states.

To find the number of years, you get y alone.

10+5y=50

5y=40

y=8 years
