Question

Kiran ate breakfast in a café. His total check was $15.

a. What’s a 20% tip?
b. How much money did Kiran spend altogether for breakfast?

Answer 1

A 20 percent tip is basically multiplying the price by 0.2

Percent means out of a hundred.
20/100 is 0.2

We have to find 0.2 of 15.

We can multiply 15 by 0.2 to find 20 percent of 15 and you would get 3.

20 percent of 15 is 3 dollars thats your answer to A

Now the total price would just be the percentage you found in A and add it to the total breakfast.
3 + 15 = 18

Kieran spend 18 dollars for brekfast.
