The sports boosters club is having a bake sale to buy uniforms. they want to raise $250. they need to rent a booth for $20. how many dozen cookies will they need to sell if they charge $3 per dozen?
which equation could be used to solve this problem?
250 = 3c - 20
250 = 3 - 20c
250 = 20 - 3c
250 = 20c - 3

250 = 3c - 20

Step-by-step explanation:

They have a goal to raise $250...  but on top of that they will also need to pay $20 for the booth... that has to be covered by the cookies sales too, ensuring they have a net balance of $250 at the end.

So, with 250 = 3c - 20, they will cover that booth expense.

But how many dozens of cookies do they have to sell to reach their goal?

250 + 20 = 3c

270 = 3c

c = 90

They need to sell 90 dozens.  Got milk? :-)

Option B: is the function

Explanation:

Given that the function has 2 connecting lines.

The first line goes from to

The second line starts at and continues horizontally at

Now, we need to determine the function.

Let us determine the function for the first line.

The coordinates are and

The slope of the first line is given by

Substituting the coordinates, we have,

Thus, slope is and y - intercept is

Substituting the slope and y - intercept in the slope - intercept formula, we have,

Hence, the function of the first line is

Now, we shall find the function of the second line.

It is given that the line continues horizontally at

Thus, the function of the second line is

Therefore, the function of the graph is given by

Hence, Option B is the correct answer.
