Jack and Mark both received hourly wage increases of 6 percent. After the wage increases Jack's hourly wage was how many dollars per hour more than Mark's?
(1) Before increase, Jack's hourly wage was 5 dollars more than Mark's
(2) Before increase, the ratio of Jack's hourly wage to Mark's hourly wage was 4:3
From 1) Let M's wage before increase = x, therefore J's = x+5
After the 6% increase M's = 1.06x and J's = 1.06(x+5)
Subtract: (1.06(x+5)) - 1.06x
Hece BCE out
2) M's wasge = x , J's = y
y/x = 4/3
Two unknows hence cannot find an answer.
Therefore answer is A
