a. write an equation that models the problem

b. solve the equation

c. write your answer in the form a sentence.

Part a)

Part b)

Part c) The toaster cost was $9.36

Step-by-step explanation:

Part a) Write an equation that models the problem

Let

x ----> the cost of the toaster

y ----> the cost of the vacuum

we know

The cost of the toaster plus the cost of the vacuum must be equal to money that Kelly spent at a yard sale

so

----> equation A

----> equation B (given problem)

substitute equation B in equation A

-----> linear equation that models the problem

Part b)  Solve the equation

we have

Solve for x

Subtract 17.55 both sides

Part c) Write your answer in the form a sentence.

The toaster cost was $9.36

y/x=18
