If tanya bought 4 items and tony bought 5 items but each was 1.25 less than the item tanya bought. but they paid the same amount of money. whats the individual cost of each person items?

Cost of one of Tanya's item = $6.25

Cost of one of Tony's item = $5.00

Step-by-step explanation:

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

Then Tanya bought 4 items. She paid M = 4*X

Tony bought 5 items. He paid M = 5 *(X - $1.25)

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

Then 4*X = 5 *(X - $1.25)

4X = 5X -$6.25

5X - 4X = $6.25

X = $6.25 Cost of one of Tanya's items

X-$1.25= $6.25 - $1.25 = $5.00 Cost of one of Tony's items.

Tanya paid 4*$6.25 = $25.00

Tony paid 5*$5.00 = $25.00

Both Tanya and Tony paid the same amount of money = $25
