On a snow day, Owen created two snowmen in his backyard. Snowman A was built to a height of 60 inches and Snowman B was built to a height of 42 inches. The next day,
the temperature increased and both snowmen began to melt. At sunrise, Snowman
A's height decrease by 6 inches per hour and Snowman B's height decreased by 3
inches per hour. Let A represent the height of Snowman At hours after sunrise and
let B represent the height of Snowman Bt hours after sunrise. Graph each function
and determine the interval of time, t, when Snowman A is taller than Snowman B
