A store selling the calculators donates $90 to charity from the profit of $500 worth of calculators. If they sell
$200 worth of calculators and donate at the same rate,
how much money would be given to charity?

Will be reveled in part B.

Step-by-step Part A

Using O P N Chart for the profits of $500

O P N represent Original, Part Percent and New original.

O $500 ║100%

P   $410║-18%

N $90   ║82%

I got $410 which is my part percent by subtracting the original by the New original. (500 - 90 = 410)

Now to solve for the part percent and New original which we will know how much money would be given to charity?

Solving for part percent

Part percent x org = Part

(X) x 500 = 90

500x = 90

500      500

x = 0.18 =  18%.

If they sell $500  worth of calculators and donates $90 to charity they are left with $410 and they gave the charity 82%

Part B:

O: $90   ║ 100%

P:   $110  ║-18%

N: $200  ║82%

So this tells me that the charity recived $110.

the answer is n
