Question

Eight friends ate at a restaurant and agreed to share the bill equally. Because Judi forgot her money, each of her seven friends paid an extra $2.50 to cover her portion of the total bill. What was the total bill?

Accepted Answer

Since Judi's 7 friends had to pay 2.50 extra each to cover the total amount that Judi should have paid, we multiply 2.507=17.50 is the bill Judi would have paid if she had money. Hence, to calculate the total amount, we multiply 17.508=140$ to find the total the 8 friends paid.
