Answer:
2.07 or 13.57
Step-by-step explanation:
First, you'd want to calculate the total bill. So you'd do the original bill multiplied by 1.18 (signaling the addition of the tip).
46 · 1.18 = 54.28
If you're calculating only the tip, it would be 46 · 0.18= 8.28
Then, since there is Martha, and 3 of her friends, you'd divide the bill (54.28) by 4 people. However, since the question is a little unclear on whether it is asking how much each person should leave for the tip, or leave overall, there are 2 possible answers.
Overall, each person would leave 54.28/4 = 13.57.
For the tip only, each person would leave 2.07.
The range is the difference between the highest and lowest numbers in the given set of numbers.
Highest number= 80
Lowest number= 28
Range
= 80 - 28
= 52
ANSWER: The range is 52.
Hope this helps! :)
$6.25 × h = c
h = hours, c = total cost
$31.25 for 5 hours. $6.25 per hour
$50 for 8 hours. $6.25 per hour
(7,5) is the solution to this system.
Based on the angles, we know this is a 45-45-90 triangle.
In this type of triangle, x and y will be equal. The formula for the sides is x * rad 2 = 8 .
8/ rad 2 = 5.66
Both X and Y are 5.66 units.
