Answer:  Each shirt costs $1.25, and each hat costs $2.5. 
Step-by-step explanation:
Let x= Cost per T-shirt, y = Cost per Hat.
As per given, 
3x+3y=11.25        (i)
4x+2y=10             (ii)
Multiply 4 to equation (i)
12x+12y=45          (iii)
12x+6y= 30             (iv)
Eliminate (iv) from (iii), we get
6y= 15
⇒ y = 2.5
Put value of y in (i)
3x+3(2.5)=11.25
⇒3x+7.5=11.25
⇒3x= 3.75
⇒x= 1.25
Hence, each shirt costs $1.25, and each hat costs $2.5.

1: 14 ft
2: 18
3: 11; 28
4: 8; 96
5: a = 5x3
6: a = 8x8
7: 1x42, 2x21, 3x14, and 6x7. 6x7 probably makes the most sense.
