Answer:
51
Step-by-step explanation:
Divide 170 by 10 you get 17,now that is 10% of 170, and 3 times 10% is 30% 10 3 times 17 equals 51.
For this case we have the following equation:

We apply distributive property on the left side of the equation:

Subtracting
from both sides of the equation:

Subtracting
from both sides of the equation:

We multiply by 3 on both sides of the equation:

We multiply by -1 on both sides of the equation:

The solution of the equation is

because u have to use the formula i hope that helps
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.
We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3
Equate P as 62.10 since we are looking for the MAX value for x (then a legitimate one if necessary)
(20 + 0.5x) + (3 + 0.075x) = 62.1
= 0.575x + 23 = 62.1
x = (62.1-23)/0.575
x = 680
