In June Corey 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

To solve this problem, let's calculate how much money Corey will save each month starting with $20 in June.

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, Corey will have saved a total of $35.43.
