Question

Kimo went into a bakery where they sell cookies for $0.75 each and brownies for $1.25 each. Kimo has $15 to spend and must buy no less than 12 cookies and brownies altogether.
a. Define the variables. (4 pts)




b. Write the system of inequalities that could be used to solve the situation. DO NOT SOLVE. (4 pts)

Answer 1

a) The variables are:

• x = number of cookies bought.
• y = number of brownies bought.

b)

x + y ≥ 12

x*$0.75 + y*$1.25 ≤ $15

How to write the system of inequalities?

a) First we need to define the variables, in this case we have:

• x = number of cookies bought.
• y = number of brownies bought.

b) Now we want to write the system, we know that he must buy at least 12 items, then:

x + y ≥ 12

And he can spend, at most, $15, then:

x*$0.75 + y*$1.25 ≤ $15

These two inequalities conform the system of inequalities:

x + y ≥ 12

x*$0.75 + y*$1.25 ≤ $15
