Answer:
8 inches of wire for 24 cents
Step-by-step explanation:
Simplify. Find the amount it costs for 1 inch of wire. Divide 45 with 15:
45/15 = 3
1 inch of wire costs 3 cents.
Now, solve for the the amount of wire (x) you can get for 24 cents
(1/3)(8/8) = (x/24)
1 x 8 = 8
3 x 8 = 24
x = 8
8 inches of wire for 24 cents
