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
