Answer: $3.16.
Step-by-step explanation:
You want to leave a 15% tip on a meal that cost $21.05.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $21.05 meal cost is.This is always done by multiplying 0.15 by $21.05, or
0.15 x $21.05=$3.16.
So, the amount of tip you are going to leave is $3.16.
I’m pretty sure it’s C. because half of 12 is 6 so if they’re buying a pound and a half it would be 12+6, which is 18
We can verify this with the graph
