B) $1.50
C) $2.40
D) $3.00

Answer 1

The cost for 20 yards of wire is determined by finding the cost per yard from the given rate and then multiplying it by 20. The calculation shows that the cost for 20 yards is $1.20. The correct answer is option A).

Step-by-step explanation:

The question asks us to calculate the cost of wire when given a specific rate. Since 2 1/2 yards cost 15 cents, we find the cost per yard by dividing 15 cents by 2.5, which gives us 6 cents per yard. To find the cost for 20 yards, we multiply 6 cents by 20, resulting in 120 cents or $1.20.

Here's a step-by-step explanation: Determine the cost per yard: 15 cents ÷ 2.5 yards = 6 cents per yard. Find the total cost for 20 yards: 6 cents per yard × 20 yards = 120 cents = $1.20. Therefore, the answer to what 20 yards of wire will cost is option A) $1.20.
