Answer to Problem 3CYP
x = 30 means to make profit Antoine`s class must sell more than 30 candy bars.
Explanation of Solution
Given:
Antoine`s class is selling candy to raise money for a class trip. They paid $45 for the candy, and they are selling each candy bar for $1.50. The function y = 1.50x − 45 represents their profit y when they sell x candy bars.
Concept Used:
Find the zero, plug in y = 0 and solve for x
Calculation:
Find the zero, plug in y = 0 and solve for x
Y is the profit and y = 0 means there is no profit.
x is the number of candy bars. x = 30 means to make profit Antoine`s class must sell more than 30 candy bars.
Thus, x = 30 means to make profit Antoine`s class must sell more than 30 candy bars.
