Question

Suppose you go out to eat with a friend and your bill was $25.67. The local sales tax rate is 7% and you want to leave a 20% tip for the waitress. Calculate the 20% tip of $25.67. [tip]

( I need the tip)

Answer 1

Umm I'm not sure is it 25...

Explanation:

Answer 2

Tip= $5.13

Explanation:

You can crossmultiply and use the "Is/Of x %/100" method

= X/$25.67 x 20%/100

Cross multiply:

25.67 x 20 = 513.4

Xx100= 100X

To solve for X from here, divide both answers by 100

513.4/100= 5.13

100X/ 100 = X

So...

$5.13 = X
