Min and Glen received $385 in total from their father. After Min spent ²₃ of her money and Glen deposited ³₇ of his money into his savings account, Min had four times as much money as Glen.

1. Find the amount of money Min received from her father.
2. If Glen' savings increased by 20% after the deposit, how much was Glen' savings in the bank in the end?

	Min	Glen	Total
Before	3x16 = 48 u	7 u	$385
Change	- 2x16 = - 32 u	- 3 u
After	1x16 = 16 u	4 u
Comparing Min and Glen in the end	4x4	1x4

Fraction of Min's money left
= 1 - ²₃
= ¹₃

Fraction of Glen's money left
= 1 - ³₇
= ⁴₇

The amount that Min had in the end is repeated.  Make the amount that Min had in the end the same. LM of 4 and 1 is 16.

Total amount given to Min and Glen
= 48 u + 7 u
= 55 u

55 u = 385

1 u = 385 ÷ 55 = 7

Amount that Min received from her father
= 48 u
= 48 x 7
= $336

(b)
Amount that Glen deposited
= 3 u
= 3 x 7
= $21

Savings that Glen had at first = 100%

Savings that Glen had in the end
= 100% + 20%
= 120%

20% of the savings = 21
1% of the savings = ²¹₂₀
120% of the savings = 120 x ²¹₂₀ = 126

Glen's savings in the end = $126

Answer(s): (a) $336; (b) $126
