Answer:
Before going to the first store he had $ 112.
Step-by-step explanation:
Before going to the first store Mr. Chin had all his money, which we will call by "x". After the first store he had:
y = x/2 - 14
He then went to a second store and he spent all his money in a way that:
y/3 - 14 = 0
Because after that store he had no money left. So we can use the second equation to solve for y and then use that value to solve for x, that is the amount of money he had before going to the first store. We have:
y/3 = 14
y = 14*3 = 42
From the first equation:
42 = x/2 - 14
x/2 - 14 = 42
x/2 = 42 + 14
x/2 = 56
x = 112
Before going to the first store he had $ 112.
