Question

You sell candy at a football game for $1.50 each. You paid $50 for 300 candy bars. what is the domain and range for your profit?

Answer 1

Domain is number of candy or 300

Range is profit from selling candy or $50

Explanation:

Domain is the numbers you are allowed to use in your function. In this case, it would be the amount of candy you sold.

The range is the output from inputting the number(s) in the domain. In this case, the range is the amount of money you profit.

Profit=(amount gained)-(amount lost)

amount gained is from selling candy

amount lost is what you invested to get the candy

amount gained=(cost per candy)X(number of candy)

amount gained=(1.50)(300)

amount gained=$450

amount lost=$50

therefore

Profit=450-40=$400

a function for profit can be as follows:

P(x)=1.5x-c

where amount you sold each candy for, c is cost for those x candies, and P(x) is the profit for x candies
