The price of Stock A at 9 A.M. was $12.98. Since then the price has been increasing at the rate of $0.07 each hour. At noon the price of Stock B rates continue, in how many hours will the prices of the two stocks be that same?

Let the hours when they equalize=h, then we have:
12.25 + .13h=13 - .09h
.13h + .09h=13 - 12.25
.22h=.75 divide both sides by .22
h=.75/.22
h=3 9/22, hours, when they will equalize.
