Question

There is a proportional relationship between the weight and total cost of a bag of cherries. One bag weighs 2.1 pounds and costs $7.98. Another bag weighs 2.8 pounds and costs $10.64.

Describe how you would graph the proportional relationship.

PLEASE HELPPP, I got like three different answers

Answer 1

y = 3.8x

Explanation:

Let y = the cost of the cherries

Let x = pounds of cherries

We can find the unit rate by either:

`(7.98)/(2.1)` = $3.80 per pound

or

`(10.64)/(2.8)` = $3.80 per pound

Now we can write the equation

hy = 3.8x
