Answer:

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

Step-by-step explanation:

Answer:

Tip= $5.13

Step-by-step 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
