Question

Two pounds of dried cranberries call $5.04 , 3 pounds of dried cranberries cost $7.56, and 7 pounds of dried cranberries cost $17.64 . Which equation gives the total cost of y of x pounds of dried cranberries.

A. y=1.68x
B. y=2.52x
C. y=3.04x
D. y=5.04x

Answer 1

The answer is B. Each lb of cranberries is 2.52
Hope this helps!

Answer 2

To solve this we have to find the unit rate.
To do that we do 5.04/3=2.52
We could also do 7.56/2.52
Or 17.64/7=2.52

So we now know the unit rate is 2.52
And there is no y-intercept so

Y=2.52x

So B is the correct answer
