Monica and Chandler had an equal amount of money at first. After Monica spent $72 and Chandler earned $12, Chandler had 4 times as much as money as Monica. How much did each of them have at first? (thanks in advance for helping to solve as my answer and the answer given was not the same and I scratching my head!)

	Monica	Chandler
Money at first	u	u
Change	– $72	+ $12
In the end	u – 72	u + 12

Since Chandler had 4 times as much in the end,

4(u – 72) = u + 12

4u – 288 = u + 12

3u = 300

u = 100

They each have $100 at first.

Check:

100 – 72 = 28

100 + 12 = 112

28 × 4 = 112
