Answer:
Number of caramels = 20
number cremes = 30 - 20 = 10
Step-by-step explanation:
Data provided in the question:
Selling cost of each box = $12.50
Number of pieces of candies held in a box = 30
Cost of producing caramel = $0.25
Cost of producing cremes = $0.45
Now,
let the number of caramels be 'x'
Thus,
Number of cremes = 30 - x
Profit = Selling price - Cost
3 = $12.50 - [ 0.25x + 0.45(30 - x) ]
or
[ 0.25x + 0.45(30 - x) ] = 12.50 - 3
or
0.25x + 13.5 - 0.45x = 9.50
or
-0.20x = 9.50 - 13.5
or
-0.20x = - 4
or
x = 20
Hence,
Number of caramels = 20
number cremes = 30 - 20 = 10
