Step-by-step explanation:
Given: Price of each red binder is $2.25.
Price of each green binder is $3.24.
Total Jackie paid is $21.96.
Lets assume the number of red binder bought be "x".
∴ Total amount paid for red binder=
⇒ Total amount paid for red binder=
Now, finding the amount paid for green binder.
As we know the total amount paid by Jackie is $21.96 and she bought same number for each binder.
Jackie paid for x number of green binder=
Next, we can write an equation on total amount paid for Green binder to find value of x.
∴
Solving the equation.
Adding both side by \$ 2.25x
⇒
⇒
cross multiplying both side.
⇒
∴ x= 4
