Answer:
Total amount earn = $31.98
Step-by-step explanation:
Given:
Cost of paper = $1.41
Cost of aluminium = $1.53
Cost of plastic = $0.33
Amount of paper = 5 pound
Amount of aluminium = 15 pound
Amount of plastic = 6 pound
Find:
Total amount earn
Computation:
Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)
Total amount earn = $7.05 + $1.98 + $22.95
Total amount earn = $31.98
Lets say there are x blue marbles.
Purple marbles = 5 + 3x
Blue marbles = x
Total = 65
5 + 3x + x = 65
5 + 4x = 65
4x = 65 - 5 = 60
x = 60/4 = 15
Blue marbles = 15
65 - 15 = 50
There are 50 purple marbles.
