Your school is raising money for a non-profit organization. The local chapter of the non-profit organization keeps 80% of the money raised, and 20% goes to the national chapter of the non-profit organization . Four of your friends each donate the same amount. The total money you raise for the local chapter of the non-profit organization is $51.20. How much does each friend donate?

The amount of money donated by each friend is $16

Step-by-step explanation:

The given parameters are;

The percentage of the money raised that is kept with the local chapter = 80%

The percentage of the money raised that goes to the national chapter = 20%

The amount of money donated by each of the four friends = Equal amount each

The total amount of the money raised for the local chapter of the non-profit = $51.20

Let x represent the amount of money donated by each of the four friends

Therefore, we have;

80% of 4 × x = 51.20, which gives;

80/100 × 4 × x = 51.20

0.8 × 4 × x = 51.20

x = 51.20/(0.8 × 4) = 16

The amount of money donated by each friend = x = $16.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

answer is b
