Brad is 49 years old and has his retirement savings in a 401(k). if he makes $82,500 annually, what is the maximum percentage of his income that he can contribute to his 401(k) plan per year? (the current maximum contribution limit is $16,500.)

An expression for the combined total dollar amount he earned this month is $(7x + 14y) where x + y = 103.

Explanation:

Let the no. of hours worked as tutor be x

Earning as tutor in 1 hour = $7

Earning as tutor in x hour = $7*x = $7x

Let the no. of hours worked as waiter be y

Earning as waiter in 1 hour = $14

Earning as waiter in y hour = $14*y = $14y

Given that total hours worked in the month = 103 hours

therefore, x + y = 103 > (1)
