 The price of Stock A at 9 A.M. was

​$14.8814.88.

Since​ then, the price has been increasing at the rate of

​$0.060.06

each hour. At noon the price of Stock B was

​$15.3815.38.

It begins to decrease at the rate of

​$0.120.12

each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

14.88  +.06(3)   +  .06x    =   15.38 - .12 x      solve for 'x' the number of hours until they are equal

15.06 + .06x   = 15.38-.12x

.18x = .32

x = 1.77 hr        ~ 1 hr  47 min
