The cheerleading squad is having a bake sale. They want to bake at least 120 cookies. They made 12 cookies the first hour and 24 cookies the second hour.

a)Write an inequality that describes the scenario. Let Variable h represent the number of hours that must bake to meet or surpass the goal.

B) How many hours must they work to meet or surpass the goal?

b. 36cookies/2hr. = 18 Cookies/hr.

T = 120Cookies * 1hr/18Cookies = 6.67 hrs.

a) To describe the scenario with an inequality, we need to consider the total number of cookies baked after each hour. Let's say h represents the number of hours the cheerleading squad must bake to meet or surpass the goal.

After the first hour, the number of cookies baked is 12.
After the second hour, the number of cookies baked is 12 + 24 = 36.

Since the squad wants to bake at least 120 cookies, we can write the following inequality:
12h + 24h ≥ 120

b) To find out how many hours they must work to meet or surpass the goal, we need to solve the inequality:
12h + 24h ≥ 120

Combining like terms, we get:
36h ≥ 120

Dividing both sides of the inequality by 36, we find:
h ≥ 120/36
h ≥ 3.33

Since we can't have a fraction of an hour, the squad must work at least 4 hours to meet or surpass the goal of baking 120 cookies.
