Two pounds of cashews cost $5, 3 pounds of cashews cost $7.50, and 8 pounds of cashews cost $20. Find the constant of proportionality. Then write an equation that represents the relationship between the cost and the number of pounds cashew.

Equation = P = 2.5 C

Step-by-step explanation:

From the first statement

2 ib = $5

1 ib = $2.5

From second statement

3 ib = $7.5

1 ib = $2.5

Hence every one pound cost $2.5

let P represent pound and C represent cost

P = 2.5 C

answer is 144
