Celia is comparing

Question

Celia is comparing two different antivirus programs. StaySafe costs $22 for the first year and $5 for each year she renews. VirusProtector costs $10 for the first year and $8 for every year she renews.

Which equation would you solve to find the number of years, y, that Celia would have to renew to make the costs of the antivirus programs equal?

Answer 1

StaySafe's equation is 22 + 5y.

VirusProtector's is 10 + 8y.

When they equal each other, that's when the costs will be equal. So the equation you want is 22 + 5y = 10 + 8y
