Answer:
The individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
Step-by-step explanation:
First we have to find 2 equations to express the problem
x = value of each item
y = total amount of money
3x = y
4 ( x - 2.25 ) = y
we replace the y by (3x) in the second equation and obtain the value of x
4 ( x - 2.25 ) = y
4 ( x - 2.25 ) = 3x
4x - 9 = 3x
4x - 3x = 9
x = 9
9 - 2.25 = 6.75
this means that the individual cost of each person’s items was $ 9 for Tanya and $6.75 for Tony
