Suppose that 15 inches of wire costs 45 cents. At the same rate, how many inches of wire can be bought for 24 cents?
2 answers:
Answer:
8 inches
Step-by-step explanation:
We can use proportions to solve this problem. Take the inches over the money.
15 inches x inches
--------------- = -----------
45 cents 24 cents
Using cross products
15*24 = x *45
Divide each side by 45
15*24/45 = x*45/45
8 =x
You can buy 8 inches
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
