Question

Kamryn is selling bracelets. It costs her $2 each week to advertise her bracelets. She buys each bracelet for $0.25 and sells them for $1.00 each. Write an equation to model the amount of profit, P, she makes from selling x bracelets in one week.
A. P = 0.75x − 2
B. P = 0.25x − 2
C. P = 0.75x + 2
D. P = 2x − 0.75

Answer 1

A. P= 0.75x-2
the answer is a because you are using 2 dollars to advertise every week so that can be represented by -2. if you make a profit of $1 for every bracelet and use $0.25 for every bracelet. you should subtract 1.00-.25 which gives you $0.75. Therefore your profit for every bracelet is 0.75.

Answer 2

Fixed cost = $2 each week

Profit from 1 bracelet = $1.00 - $0.25 = $0.75
Profit from x bracelets = $0.75x

Total profit, P = 0.75x - 2
