Answer:
$21.80
Step-by-step explanation:
50% of 38 is 19. 10% of 38 is 3.8. Add these together to get 21.8. This equates to $21.80.
A cube has six sides so you divide 3750 by 6 to find the area of a single face. This would be 625. Area is length times width and since it is a cube you know that both are the same. This gives you an answer of 25.
