In June, Cory begins to save money for a video game and a TV he wants to buy in December. He starts with $20. Each month he plans to save 10% more than the previous month. How much money will he have at the end of December?

Question

A. $154.31
B. $251.59
C. $228.72
D. $189.74

Answer 1

To solve this problem, we need to calculate Cory's savings for each month from June to December.

June: $20
July: $20 + 10% of $20 = $20 + $2 = $22
August: $22 + 10% of $22 = $22 + $2.20 = $24.20
September: $24.20 + 10% of $24.20 = $24.20 + $2.42 = $26.62
October: $26.62 + 10% of $26.62 = $26.62 + $2.66 = $29.28
November: $29.28 + 10% of $29.28 = $29.28 + $2.93 = $32.21
December: $32.21 + 10% of $32.21 = $32.21 + $3.22 = $35.43

At the end of December, Cory will have $35.43. Therefore, the closest option is D. $189.74.
