Question

Graham puts 20 in his piggy bank every week. At the end of 39 weeks, he adds100 to the piggy bank money and decides to do the following: buy some clothes and sports gear for 314.23, buy his mom a present for123, and divide the rest of the money equally among his three brothers. Use a calculator to find the amount of money each brother will get.

1) $147.59
2) $260.25
3) $293.13

Answer 1

Graham saved a total of $890 over 39 weeks. After spending $314.23 on clothes and sports gear and $123 on a present for his mom, he had $452.77 left to divide among his three brothers. Each brother will receive $150.92.

Step-by-step explanation:

The student has asked how much money each of Graham's three brothers will get after he saves money for 39 weeks and makes certain purchases. Graham saves $20 every week for 39 weeks and then adds an additional $100 to his savings. After making purchases totaling $314.23 (for clothes and sports gear) and $123 (for his mom's present), he divides the remaining money equally among his three brothers. We can calculate the total amount saved, subtract the amount spent, and then divide the remainder by three to find the amount each brother will receive.

First, we calculate the total amount saved:
20 (dollars per week) × 39 (weeks) + 100 (additional amount) = $890

Then, subtract the total amount spent on purchases:
890 - 314.23 (clothes and sports gear) - 123 (mom's present) = $452.77 remaining

Finally, divide the remaining amount by three to find out how much each brother will get:
452.77 ÷ 3 = $150.92 per brother

Answer 2

To find the amount of money each brother will get, we need to calculate the total amount of money Graham has in his piggy bank and subtract the total amount spent. Then, we divide the remaining money equally among the three brothers.

Step-by-step explanation:

To find the amount of money each brother will get, we need to first calculate the total amount of money Graham has in his piggy bank. Graham puts $20 in his piggy bank every week for 39 weeks, so he saves a total of $20 x 39 = $780. He then adds $100 to the piggy bank, making the total amount of money $780 + $100 = $880.

Graham spends $314.23 on clothes and sports gear and $123 on a present for his mom, so the total amount spent is $314.23 + $123 = $437.23. To find the amount of money each brother will get, we need to subtract the total amount spent from the total amount of money, and then divide the remaining money equally among the three brothers. So, the amount each brother will get is ($880 - $437.23) / 3 = $142.59. Therefore, option 1) $147.59 is the correct answer.
