Question

Garrett started his coin collection when his grandfather gave him 34 coins. Every month after that, his grandfather gave him 6 more coins to add to it. How many coins did Garrett have in his collection after 30 months?

Answer 1

34 + 6m = total coins (t)....where m represents number of months

After 30 months.....m = 30
34 + 6(30) = t
34 + 180 = t
214 = t.....so after 30 months, Garrett had 214 coins in his collection
