Amy's mother ordered a pizza to be delivered to their home. The bill for the pizza was $18. She gave the delivery man a 15% tip. How much was the tip?
The tip was $2.70.
To calculate the tip amount, you can multiply the bill by the tip percentage expressed as a decimal:
$18 x 0.15 = $2.70
18x.15=2.702.70+18=20.70
tip=$20.70
I'm sorry, but that is not correct. The correct tip amount is $2.70, not $20.70.
You first need to calculate the tip amount by multiplying the bill ($18) by the tip percentage (15%), expressed as a decimal (0.15):
Tip = $18 x 0.15 = $2.70
Then, you can calculate the total amount paid by adding the bill and the tip:
Total = $18 + $2.70 = $20.70
So the correct answer is that the tip was $2.70, and the total amount paid was $20.70.
Which is equivalent to 13 - 33?
13 - 33 = -20
Therefore, -20 is equivalent to 13 - 33.
What is the value of n2(m+r) if m=3, n=2, and r=4?
If we substitute m = 3, n = 2, and r = 4 into the expression n^2(m + r), we get:
n^2(m + r) = 2^2(3 + 4) = 2^2(7) = 4(7) = 28
Therefore, the value of n^2(m + r) when m = 3, n = 2, and r = 4 is 28.
