You are buying packages of beads to make bracelets. Each package costs $3 plus 7% tax. You have a gift card for $15, and you plan to use only the gift card to pay for the beads. Which function c(p) represents the total cost, where p represents the number of packages of beads you purchase? What is a reasonable domain?

c(p) = 3.00p * 1.07
since c <= 15,
3.00p*1.07 <= 15.00
p <= 5/1.07 = 4.67

So, a max of 4 packages can be purchased
