Answer 1

Inequality
`4x\geq 200`

Solution
`x\geq 50`

Refer the attached figure.

Explanation:

Given : The Math Club is sponsoring a bake sale. If their goal is to raise at $200.

To find : 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?

Solution :

Let the number of sold pies be x.

The goal is to raise atleast $200.

They sell pie at $4 each.

The inequality that represent the situation is

`4x\geq 200`

Now, We solve the inequality we get

`4x\geq 200`

Divide by 4 both side,

`x\geq 50`

The solution is the interval [50,∞)

i.e, All positive whole numbers greater than or equal to 50

Refer the attached figure below represent the inequality with help of graphing tool.

Answer 2

If the math club is sponsoring a bake sale and the goal is to raise $200.00, The equation would be
number of pies needed to meet that goal = $200.00 / $4.00
Therefore,
The answer is 50 pies.
