Answer:
$15
Step-by-step explanation:
Let A, B, C and D represent the four friends respectively.
<u>Given the following data;</u>
Amount earned by A = $15
Amount earned by B = $20
Amount earned by C = $25
Amount earned by D = $40
Total amount earned = 15 + 20 + 25 + 40
Total amount earned = $100
For an equal ration, each friend should be given;
Each earnings = total amount earned/number of friends
<em>Substituting into the equation, we have;</em>
Each earnings = 100/4
Each earnings = $25
Hence, for D with $40, would become;
D = $40 - $25
D = $15
<em>Therefore, D would give A $10 and give B $5.</em>
It would be much easier for me to help you pick the correct equation
if you would let me see the list of choices.
Since I can't see any of the choices, I'll just make up a few equations
that have the ordered pair (24, 6) as a solution:
Y = 0.25 x
Y = x - 18
Y = 0.5 x - 6
Y = 0.1 x + 3.6
