Question

The dinner check was 65.00$ if Denver gave the server a 25% tip how much did he spend in all?.

Answer 1

Start by finding to total amount of the tip:


`Tip = rate * base`

`T=rb`

`T=25\%*$65`

`T=0.25*65`

`T=$16.25`

And then add the two together: $65 + $16.25 = $81.25

You can also do it another way by realizing that in total they payed 125% of what the dinner cost:

`Total=125\%*csot`

`T=1.25c`

`T=1.25*65`

`T=$81.25` same as above.
