A store charges $7.00 for 2 pounds of gummy worms, $10.50 for 3 pounds of gummy worms, and $24.50 for 7 pounds of gummy worms. Write an equation that represents the total cost (y) of any number of pounds (x) of gummy worms.

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
