Question

Write a proportion: At a candy store, it costs $0.25 to buy 5

inches of rope candy. Write an equation to find x, the length
of rope candy that can be bought for $1.80?

Answer 1

Answer: 36

Explanation:

.25/5 = .05

1.80/.05 = 36

Answer 2

The proportion is:

$0.25 / 5$ inches $= x / $ inches bought for $1.80

Simplifying the left-hand side:

$0.25 / 5 = 0.05$

The equation to find x becomes:

$0.05 = x / 1.80$

To solve for x, we can multiply both sides by 1.80:

$0.05 \cdot 1.80 = x$

$x = 0.09$

Therefore, the length of rope candy that can be bought for $1.80 is 0.09 inches.
