Question

Ms. Roth has made 200 headbands and is deciding what price to charge for them. She knows that she will sell more if the price is lower. To estimate the number she can expect to sell, she uses the function N defined as N(p)=200−1.5p, where p is the price in dollars.

Which choice describes a function, S(p), that models the total sales in dollars she can expect?

1. S(p)=p⋅N(p)

S(p)=p(200−1.5p)

2. S(p)=p+N(p)

S(p)=200−0.5p
3. S(p)=p−N(p)

S(p)=2.5p−200

4. S(p)=N(p)−p

S(p)=200−2.5p
