Ronald's bill at the end of his lunch was $24.00. Using a proportion, determine the amount of his bill that he must leave for a 19% tip. A.
$24.19
B.
$28.56
C.
$4.08
D.
$4.56

Ok so break up the 19% into three parts 10% 5% and 4 1%

10 percent of 24 is 2.40 (move decimal point one over)

5 percent is half of that which would be 1.20

1 percent is .24 (move decimal point over twice) that 4 times is .96

2.40+1.20+0.96=4.56

Hope this helps
