Question 1207745
Let number of caramelsbe  x 
 and number of cremes in the box be y

Candies in each box = 30
x+y=30

The caramels cost $0.25 to produce and the cremes cost $0.45 

One box sold for $12.50
Profit  goal $3.00 
Cost should be $9.50

Cost of candies  equation

0.25x+0.45y=9.50
Multiply equation by 4

x+1.80y =38
x+y=30
Subtract the equations

0.80y  =8

y=10
x=20

 each box should contain:

20 caramels
10 cremes
