Answer:
$27.60
Step-by-step explanation:
First, we need to find how much the tip is:
we can convert 15% directly to a decimal:
15% = 0.15
Then we find :
15% of 24 = 0.15 x 24 = 3.59999999999999
3.599999999999999 to the nearest cent is 3.60
Then we add the tip to the original bill:
3.60 + 24 = 27.60
So the total cost of the lunch is $27.60
