Question

Part a

If Mary buys 7 pounds of peanut butter fudge how much will it cost?

Part b

The equation y = 5.20x represents the relationship between total cost and pounds of peanut butter fudge.
What is the constant of proportionality?

Answer 1

she would pay $36.40 for 7 pounds of pb fudge the constant of proportionality would be 5.2

Answer 2

A) if 3.5 fudge is 18.20 then 3.5 times 2 is 7 then 18.20 times 2 is 36.40 which is how much it will cost.
B) i believe it would be 5.20x because it’s always changing at that rate
