Question

Jane and her friends meet for pizza once a week. They always leave the waiter a tip that is a percent of the total bill. This week the bill comes to $28.

P=% tip
t=tip left for waiter

Answer 1

The number may be 7 ;)

Answer 2

 p%(28) = t

for example, lets say u left a 5% tip
 0.05(28) = t......of course u would change the percent of ur tip to a decimal
1.40 = t.......so u would be leaving a tip of $ 1.40
