(a) write an equation. let x represent the cost of one of tanya's items. (b) solve the equation. show your work. (c) check your solution. show your work. (d) state the solution in complete sentences.

Part a)

Part b)

Part c) see the explanation in Part c)

Part d) see the explanation in Part d)

Step-by-step explanation:

Part a) Write an equation

Let

x -----> represent the cost of one of Tanya's items

y ----> represent the cost of one of Tony's items

we know that

Tanya bought 3 items -----> 3x

Tony bought 5 items -----> 5y----> 5(x-1.50)

If Tanya and Tony paid the same amount of money

then

The cost of three of Tanya's items is equal to the the cost of five of Tony's items

so

Part b) Solve the equation

we have

Solve for x

distribute the right side

Group terms that contain the same variable

Combine like terms'

Divide by 2 both sides

Find the value of y

Part c) Check your solution

substitute the value of x in the originally equation

----> is verified

Part d) State the solution in complete sentences

we have that

The cost of one of Tanya's items was $3.75

Tanya paid $11.25 for 3 items

The cost of one of Tony's items was $2.25

Tony paid $11.25 for 5 items

Tanya and Tony paid the same amount of money
