They are making Ricardo 3/4 as many shelves as they are making for Anthony. Maria is getting four more shelves than her brother Ricardo.

How many shelves are being made for each person?

i know that the total shelves being made is 24 but im not sure about how many each person is getting. :confused:

Make an equation like this:

Amount of shelves Anthony gets = X

Ricardo = (3/4)*X

Maria = (3/4)*X + 4

Now, Anthony + Ricardo + Maria = 24 which means that

X + (3/4)*X + (3/4)*X + 4 = 24

(5/2)*X = 20

X = 20 * (2/5) = 8

So, Anthony gets 8 shelves.

Ricardo gets (3/4)*8 = 6

Maria gets "Ricardo" + 4 = 10

To check the result, we add 10 + 6 + 8 = 10 + 14 = 24

So our calculation is correct.
