Question

Graham puts $20 in his piggy bank every week. At the end of 39 weeks, he adds $100 to the piggy bank money and decides to do the following:
1. Buy some clothes and sports gear for $314.23
2. Buy his mom a present for $123 3.

Divide the rest of the money equally among his three brothers.

Answer 1

weekly savings: 20 x 39 weeks = 780

additional fund: 780 + 100 = 880

bought clothes and sports gear = 880 - 314.23 = 565.77

bought his mom a present = 565.77 - 123 = 442.77

divide the rest equally among his 3 brothers = 442.77 / 3 = 147.59

Answer 2

Answer: If we divide the remaining in 3 brothers, then the money receives by each brother =  $\ 147.49$

Step-by-step explanation:

Given: The amount Graham puts in his piggy bank every week = $20

At the end of 39 weeks, the amount in piggy bank=$39\times\ 20+\ 100=\ \ 780+\ \ 100=\ \ 880$

Total spending =$\ 314.23+\ 123.3=\ 437.53$

The money left after shopping = $\ 880-\ 437.53=\ 442.47$

If we divide the remaining in 3 brothers, then the money receives by each brother =  $\ 442.47\div3=\ 147.49$
