John gets paid every Friday. One fourth (1/4) of his gross pay goes to taxes. In addition, he has payroll deductions of $75 for insurance and $125 for a car payment. Then he gives one-tenth (1/10) of the remaining money from his pay to charity. If his net pay after all these deductions (taxes, insurance, car payment and charity) is $900, what is his gross pay?

Try using what you learned back in algebra:
You're trying to find the gross pay, so this is the unknown (and is also the thing in terms of which the other items are stated), so pick a variable for the gross pay; say, "g".
You know that the taxes are 1/4 of ("times") the gross pay. Create an expression for this (here).
You know that his donation is 1/10 of ("times") the remainder, after the other deductions. The other deductions are:
. . . . .(fixed deductions) and ((1/4) of (gross pay))
...so the entire situation is:
. . . . .[(gross) less (fixed deductions) less ((1/4) of (gross))] - ((1/10) of [bracketed expression]) is (net pay)
What equation does this generate? When you solve the equation, what value do you get?
Please be complete. Thank you!
