Answer:

Gina has $37.50

Step-by-step explanation:

We know that Gina has twice as much money as Maria + 15$.

We also know that Gina gave away 30$, which left her with Half as much money as Maria. Now we have to divide 15/2 and get 7.5. 7.5 + 30 = 37.50.

Therefore, Gina has 37.50 dollars in total.

Answer:

55$

Step-by-step explanation:

The two main equations are:

G=15+2M

G-30=1/2(M+30)

15+2M-30=1/2(M+30)

2M-15=1/2(M+30)

4M-30=M+30

3M=60

M=20

Now, if you put 20 as M, this is what you get:

G=15+2*20

G=$55

M=$20
