You are at a restaurant and the check comes to a total of $49. If you want to leave a 19% tip, how much total money should you pay, to the nearest cent?

$58.31

Step-by-step explanation:

First, find the tip.

Multiply the tip rate by the check total.

tip = tip rate * check total

The tip rate is 19% and the total is $49.

tip = 19% * $49

Convert 19% to a decimal. Divide 19 by 100 or move the decimal place 2 spots to the left.

19/100=0.19                or               19.0  -->  1.9  -->  0.19

tip = 0.19 * $49

tip= $9.31

Next, find the total.

Add the tip to the check total.

total = tip + check total

The tip is $9.31 and the check total is $49.

total = $9.31 + $49

total= $58.31

The total with tip is $58.31

a = 11 : 4

b = 38

c = 1 for every 6
