Question

Jack was out at a restaurant for dinner when the bill came. His dinner came to $14. He wanted to leave a 31% tip. How much was his meal plus the tip, before tax, in dollars and cents?

Answer 1

1) turn percent into decimal

`=31` ÷
`100`

`=0.31`

2) multiply decimal by original cost to find how much to tip

`=14` ×
`0.31`

`=4.34`

3) add costs together

`=14+4.34`

= $18.34

Answer 2

The tip was $4.45 and the total of the bill and tip is $18.34
