Joey earns $12 an hour. Blake earns $16 per hour. Joey receives a raise of $1.50 every six months, and Blake receives a raise of $0.50 every six months.. Which equation can be used to find x, the number of six month intervals it will take Joey to earn hourly the same as Blake?

A) 12x + 1.5x = 16x + 0.50x
B) 12x + 1.5x = 16 + 0.50
C) 12 + 1.5x = 16 + 0.50x
D) 12x + 1.5 = 16x + 0.50
( I thought it was D at fist but i am not so sure anymore.i would mean a lot if you can help me out :)

6= x- 25%

x= 6/0.75

x= 8 km
