Question

Shea sells bracelets at the farmers market for each bracelet she sells,she spends $1.50 on beads and $3.00 on hardware. She also pays $10 per day to rent a booth. Wrote an expression that repersents Sheas total expenses for selling x bracelets in 4 days.

Answer 1

C(D) = 10D + 1.5B + 3H

C(4) = 10(4) + 1.5B + 3H

c = total cost as a function of D = number of days and B=beads and H=hardware for a bracelet

or

C(4) = 40 + 4.5b where b = number of bracelets
