Question

A 3-pound bag of apples costs $5.25. What is the unit price of a pound of apples? per pound At this rate, how many pounds of apples can be purchased for $17.50? pounds of apples Let x represent the number of pounds of apples and y the total cost of the apples. What is the equation that represents the direct variation between the total cost of the apples and the number of pounds of apples?

Answer 1

$1.75 per pound of apples, 10 apples can be purchased for $17.50 because you divide 17.50 by 1.75 since that is your unit rate per pound.

Answer 2

Cost of 3 pounds of apples = $5.25

Cost of unit pounds of apples =
`(5.25)/(3)= 1.75` dollars.

So, price is $1.75 per pound.

At this rate, how many pounds of apples can be purchased for $17.50

Amount of apples =
`(17.50)/(1.75)=10` pounds

Let x represent the number of pounds of apples and y the total cost of the apples.

So, the equation that represents the direct variation between the total cost of the apples and the number of pounds of apples

`y=1.75x`
