Answer:
- Shirt costs $10.50, pants cost $27
Step-by-step explanation:
<h3>Set equations as follows</h3>
- 3s + 2p = 85.5
- 4s + 3p = 123
<h3>Solve the system by elimination</h3>
Multiply the first equation by 4 and the second one by 3 and subtract equations
- 4(3s + 2p) - 3(4s + 3p) = 4(85.5) - 3(123)
- 12s + 8p - 12s - 9p = 342 - 369
- - p = - 27
- p = 27
Find the value of s
- 3s + 2*27 = 85.5
- 3s + 54 = 85.5
- 3s = 85.5 - 54
- 3s = 31.5
- s = 31.5/3
- s = 10.5

Step-by-step explanation:
The surface area of an object will be all of it's side area's added up.
Looking at this, we can see that there are 4 sides with side lengths 2 and 5, and 2 with side lengths 2 and 2.
The area of a rectangle is it's length times width.
Since there are 4 of these sides:
.
Since there are two of these sides:
.
