Question

The Math Club is sponsoring a bake sale. If their goal is to raise at least $200, how many pies must they sell at $4.00 each in order to meet that goal? Write, solve, and graph an inequality that represents this situation

Answer 1

Answer:

The Math Club must sell at least 50 pies to reach the goal

The graph in the attached figure

Step-by-step explanation:

Let

x-----> the number of sold pies

we know that

The inequality that represent the situation is

$4x\geq 200$

Solve for x

Divide by 4 both sides

$x\geq 200/4$

$x\geq 50\ pies$

The solution is the interval ------> [50,∞)

All positive whole numbers greater than or equal to 50

In a number line the solution is the shaded area at right of x=50 (close circle)

The Math Club must sell at least 50 pies to reach the goal
