Answer:
The shirt is $31.50 and the pants are $46.50
Explanation:
Let x represent the cost of the pants.
If the shirt is 15 dollars less than the pants, its cost can be represented by x - 15.
Create an equation, and solve for x:
(x) + (x - 15) = 78
2x - 15 = 78
2x = 93
x = 46.5
So, the pants are $46.50.
Subtract 15 from this to find the cost of the shirt:
46.50 - 15
= 31.50
The shirt is $31.50 and the pants are $46.50
