Question

The Spanish Club is selling churros as a fundraiser. If its goal is to raise at least $150, how many churros must it sell at $1.25 each to meet that goal? Write and solve an inequality.

a. 1.25c=>150; c=>120
b. 1.25c=>150; c=>100
c. 150c=>1.25; c=>120
d. 150c=>1.25; c=>25

Answer 1

The correct inequality to represent the Spanish Club's fundraiser goal is 1.25c ≥ 150. Solving for c gives c ≥ 120, meaning that at least 120 churros must be sold at $1.25 each to meet the goal of raising at least $150.

Step-by-step explanation:

The student needs to determine how many churros must be sold at $1.25 each in order to raise at least $150. Let's denote the number of churros to be sold as c. The total revenue generated from selling churros would be $1.25 multiplied by c. The inequality can be written as 1.25c ≥ 150, reflecting that the revenue from selling churros should be at least $150. To find the minimum number of churros that must be sold, we solve for c:

1.25c ≥ 150
→ c ≥ 150 / 1.25
→ c ≥ 120

Therefore, at least 120 churros must be sold to meet the fundraiser goal. The correct answer is then option a: 1.25c ≥ 150; c ≥ 120.
