Question

Your friends ate at a restaurant and left a $2.40 tip. They left a 15% tip. What was the cost of their bill before the tip?

Answer 1

16
To show work divide 2.4 by 3 to get .8 then multiply it by 20 to get 16

Answer 2

Answer:

16$ is the bill

Step-by-step explanation:

so 2.40 is 15% of the bill, what i'd do is first divide 2.40(15%) by 3 to get 5% which can make this much easier, 2.40÷3=0.80. this means that 1.60 is 10% since 0.80 is 5%. so now we do 1.60×10=16$
