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

Answer:

Cost of 3 pounds of apples = $5.25

Cost of unit pounds of apples = $\frac{5.25}{3}= 1.75$ 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 = $\frac{17.50}{1.75}=10$ 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

$y=1.75x$

Answer 2

$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.
