The French club is sponsoring a bake sale. If their goal is to raise at least $140, how many pastries must they sell at $3.50 each in order to meet that goal? Write and solve an inequality.

Question

3.50p ≥ 140; p ≥ 40

140p ≥ 3.50; p ≥ 40

3.50p ≥ 140; p ≥ 136.5

3.50p ≥ 140; p ≥ 490

Answer 1

To determine how many pastries (let's denote this number as \( p \)) the French club needs to sell, we can set up the inequality based on their goal of raising at least $140 with each pastry priced at $3.50.

The inequality can be set up as follows:

\[ 3.50p \geq 140 \]

Now, we will solve the inequality for \( p \):

1. Divide both sides by 3.50:

\[ p \geq \frac{140}{3.50} \]

2. Calculate the right side:

\[ \frac{140}{3.50} = 40 \]

Thus, the solution to the inequality is:

\[ p \geq 40 \]

This means the French club must sell at least 40 pastries to meet their goal of raising at least $140.

So, the correct answer is:

3.50p ≥ 140; p ≥ 40.
