Question

A roller coaster starts out at a height of 100 feet. It

then drops 43 feet, loops around, drops another 29
feet and finally increases 10 feet to the exit platform.
a. Write an expression to represent this.
b. Then determine the altitude of the exit platform.

Answer 1

Explanation:

a) x = 100 - 43 - 29 + 10

b) 100 - 43 = 57.

57 - 29 = 28.

28 + 10 = 38.

38 feet.
