Suppose a room service waitress at the Sand and Sand Resort receives gratuity represented by the equation g=0.15b, where g represents the gratuity and b represents the food bill. If the food bill is $19, How much tip did she receive?

$2.85

Step-by-step explanation:

So you have the equation g = 0.15b and you have that the food bill is $19, which would mean b = 19.

Then, you just have to plug that into the equation which would look like this:

0.15 * 19 = $2.85, so the gratuity, or tip, is $2.85
