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?

Step-by-step explanation:

The funtion is:

C(p)= 3(p)+1.07 (1)

where: 3 is the package cost, p is the number of packages and 1.07 is the taxes

the cost could be equal or less than the gift card value so:

C (2)

Replace 2 en 1

x 1.07

3(p)

14.02\\\\p\leq \frac{14.02}{3} \\\\p\leq 4.67" alt="\leq" />14.02\\\\p\leq \frac{14.02}{3} \\\\p\leq 4.67" />

It´s important to aprox the quantity to the minimum value so I can buy 4 packages

The reasonable domain is for all R because any number is a possible value of the independent variable

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
