Question

explanation:
the band charged $2 per bracelet at the craft fair, and they spent $200 on supplies.
profit = selling price - cost price
to find the selling price, multiply the number of bracelets sold by the cost of one bracelet.
selling price = 2b
cost price = $200
profit on b bracelets: f(b) = 2b - 200

part c
suppose the group sells exactly 100 bracelets. what will be the profit from sales?
show or explain how you got your answer.

Explanation:

Step1: Identify the profit function

We know the profit function is \( f(b) = 2b - 200 \), where \( b \) is the number of bracelets sold.

Step2: Substitute \( b = 100 \) into the function

Substitute \( b = 100 \) into \( f(b) = 2b - 200 \). So we have \( f(100)=2\times100 - 200 \).

Step3: Calculate the value

First, calculate \( 2\times100 = 200 \), then \( 200-200 = 0 \).

Answer:

The profit from selling 100 bracelets is \(\$0\).
