Answer 1

Answer:

Cost of one of Tanya's item = $9.00

Cost of one of Tony's item = $6.75

Step-by-step explanation:

Let X represent the cost of one of Tanya's item

Then Tanya bought 3 items. She paid M = 3*X

Tony bought 4 items. He paid M = 4 *(X - $2.25)

Both Tanya and Tony paid the same amount of money, then

3*X = 4 *(X - $2.25)

3X = 4X -$9.00

4X - 3X = $9.00

X = $9.00 Cost of one of Tanya's items

X-$2.25= $9.00 - $2.25 = $6.75 Cost of one of Tony's items.

Tanya paid 3*$9.00 = $27.00

Tony paid 4*$6.75 = $27.00

Both Tanys and Tony paid the same amount of money = $27

Answer 2

Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items.

Hope this helps
