If pg=50 and gr = 15, then what is the value of g (p+r)

We are asked to solve for the value of g (p+r) when pg=50 and gr=15. The solution is shown below:

pg is the same with gp

pg = gp

gr is the same with rg

gr=rg

Hence, we have:

g (p+r), distributive property

gp + gr = pg + gr = 50 + 15 = 65

The answer is 65.
