Answer:
The tip would be worth $2.19
Step-by-step explanation:
x - is the full bill
1/20 x = $0.73
Solve for x:
Multiply both sides by 20.
<u>20</u>*(1/20 x) = <u>20</u>*(0.73)
x = 14.6
Now we just have to find 15% of x to find the tip.
3/20 (14.6) = 2.19
So, the tip would be worth $2.19

Step-by-step explanation:
I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.

To obtain the Difference between Sweden and United States high and medium categories to the nearest %
Sweden :
High category = $23.51
Medium category = $15.73
United States :
High category = $34.48
Medium category = $22.46
Percentage Difference :
High category : (34.48 - 23.51) / 34.48 * 100% = 31.8%
Medium category : (22.46 - 15.73) / 22.46 * 100% = 29.96% = 30.0%
The only way to determine whether or not an outcome is unusual or not is to compare it with previous or future outcomes.
