Abraham has visited 10 countries already. he uas a goal of visiting at least 50 countries. he plans to achieve this goal by visiting 5 new countries per year(y) for the next several years.
how many years will it take Abraham to meet his goal?
Abraham already visited 10 countries so take 50 - 10 to get 40. Next divide 40 by five (since that's how many countries he plans to visit each year) to get 8.
