It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate: How many pounds of potatoes are needed to make 50 pounds of mashed potatoes?

Step-by-step explanation:

You need to set up a proportion.

10 pounds of potatoes/15 pounds of mashed potatoes

Before going on notice that the potatoes are on the top part of the fraction and the mashed potatoes are on the bottom. The right hand side of the proportion must be the same.

10 pounds potatoes/15 pounds mashed = x pounds / 50 pounds mashed.

The raw potatoes are on the top, The mashed is on the bottom. It's always like that.

The second step is to cross multiply.

10 / 15 = x / 50          Cross miultiply

10*50 = 15 * x            Combine the left

500 = 15x                  Divide by 15

500/15 = x

x = 33.33

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
