Question

Libby donated​ $50 during the first month of the year. If she makes three additional donations of equal amounts during the​ year, how much will she need to donate each time to be in the Silver​ category?

Answer 1

She will donate P-50/3 each time

Step-by-step explanation:

Now assuming total donation needed to be in the silver category Is P

We can assume also the three additional and equal donations be Q

So

Then 50 + 3Q = P

So we still don't know P

We can get Q by saying

3Q= P - 50

Q = (P - 50) /3
