Q15. Ken earned x dollars at his part-time job on Friday. His wife earned $12 more
mafiozo [28]

Ken earns 54 dollars at his part-time job on Friday

Given that Total amount earned by ken and his wife at their part-time job on Friday= $174

Money earned by ken= x dollars

Money earned by ken's wife = (2x+12) dollars

Total amount earned by ken and his wife at their part-time job on Friday=  x dollars + (2x+12) dollars

(x + 2x + 12 ) dollars = $ 174 ( addition of ken and ken's wife income and total amount earned by ken and his wife at their part-time job on Friday is $174)

(3x + 12 ) dollars = $ 174

3x=$162

x=\frac{162}{3}

x= 54 dollars

Therefore,54 dollars were earned by ken  at his part-time job on Friday

Hence,Ken earns 54 dollars at his part-time job on Friday
