Answer:

50

Step-by-step explanation:

Assuming you're solving for Q, the first step is to multiply the first set of parenthesis by 0.10:

0.10(72-Q) = 7.2 - 0.1Q

The next step is to combine the terms that have Q in them:

7.2 - 0.1Q + 0.25Q = 14.7

7.2 + 0.15Q = 14.7

Now isolate 0.15Q:

0.15Q = 14.7 - 7.2

0.15Q = 7.5

Divide 7.5 by 0.15 to solve for Q:

Q = 7.5/0.15 = 50
