Answer:
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
