Question

Mary got a piggy bank as a gift with X cents in it. If she saves Y cents each month for a year, how much money will she have in a year?

Answer 1

The total money she saved in a year = X + 12Y.

Explanation:

Mary got a piggy bank as a gift.

Sum of money in the piggy bank while she got it as a gift = X cents

Sum of money she saved = Y cents per month

1 year = 12 months

So, sum of money she saved in 1 year = Y × 12

= 12Y

Hence, the total money she saved in a year = X + 12Y.
