Answer: Let x represent the cost of one of Tanya's items.
Then the cost of one of Tony's items =x - 2.25. But we have:
3x =4(x - 2.25)
3x =4x - 9 subtract 3x from both sides
0 =x - 9 add 9 to both sides
x=$9 The cost of one of Tanya's items
27 Total cost of Tanya's 3 items
2.25 =$6.75 cost of one of Tony's items.
27 Total cost of Tony's 4 items.
3 x 6.75 =$27. This shows that both Tony and Tanya spent the same amount of money.
