Question 462013
Let x represent the amount of his paycheck. If he puts 12% into the IRA then you would multiply the amount of his paycheck, x, by .12.
{{{.12x}}}  Since you are given the amount of the contribution to the IRA, you can set this value equal to .12x
{{{.12x=72}}} Now solve for x, by dividing both sides of the equation by .12.
{{{x=600}}} So his paycheck is $600.
