Answer:

Cost of 18 pounds candy = $22.5

Cost of 10 pounds candy = $12.5

Cost of 1 pound of candies = $1.25

Step-by-step explanation:

6 pounds of butterscotch candies cost $7.50

⇔ 1 pound of same candy costs [tex]\frac{7.50}{6} =[/tex] $1.25

Now, we need to find the cost of 18 pounds of candy:

as, the cost of 6 pounds candy = $7.50

⇔ Cost of 6 x 3 = 18 pounds candy = $7.50 x 3 = $22.5

Cost of 10 pounds candy = 10 x (Cost of 1 pound candy)

= 10 x ($1.25) = $12.5

The unit rate for butterscotch candies = Cost of 1 pound of candies

= $1.25
