Question

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.

Answer 1

To find out how many pastries must be sold to meet the goal of raising at least $140, we can set up an inequality.

Let \( x \) be the number of pastries sold. Each pastry sells for $3.50, so the total amount raised from selling \( x \) pastries is \( 3.50x \).

The goal is to raise at least $140, which gives us the inequality:

\[ 3.50x \geq 140 \]

Now, we can solve for \( x \):

1. Divide both sides of the inequality by 3.50:

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

2. Calculate the right side:

\[ x \geq 40 \]

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