Answer: The sweater cost $45
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
- M = money Park has
- He spent 1/3 of his money on a sweater = 1/3 M
- He spent 3/5 of the remainder on a pair of jeans = (1 -1/3) 3/5 = 2/3 *3/5 M
- Money left = 36
So, we have to add the costs of the sweater and the jeans. That expression must be equal to the total money he has minus 36 (money left)
1/3 M + 3/5 * 2/3 M = M - 36
Solving:
1/3 M + 6 / 15 M = M - 36
11 / 15 M = M - 36
11/15 M -M =-36
-4/15 M =- 36
M = -36 / (-4/15)
M = 135
Sweater costs 1/3 M =1/3 ( 135) = $45
