Answer:
1 skateboard will cost $73 and the other will cost $72
Step-by-step explanation:
Skateboard A (Original) = X
Skateboard B (+$1) = X + 1
Solving for X
(x + 1) + x = 145
2x + 1 - 1 = 145 - 1
2x = 144
2/2 = x
144/2 = 72
x = 72
TSA of a cuboid= 2(lb+bh+lh)
= 2(5×4+4×1.5+5×1.5)
= 2(20+6+7.5)
= 2× 33.2
= 66.4 square units
