Answer:
$ 3051
Step-by-step explanation:
Original cost = $ 1000
Marked up Price = Original cost + 170% of 1000
= 1000 + 1.7 * 1000
= 1000 + 1700
= $ 2700
Sales tax = 13% of 2700
= 0.13 * 2700
= 351
Total cost paid by Bernie = 2700 + 351 = $ 3051
Answer:
Step-by-step explanation:
Let x be the speed of Savanna's truck. ?Time taken to travel 300 miles = 300/x
Tony's car speed = distance/time 280/(x-2)
Given that Tony is faster than Savannaby 20 mph
i.e. ![\frac{280}{x-2} -\frac{300}{x} =20](https://tex.z-dn.net/?f=%5Cfrac%7B280%7D%7Bx-2%7D%20-%5Cfrac%7B300%7D%7Bx%7D%20%3D20)
cancel 20 on both sides and simplify
![\frac{14}{x-2} -\frac{15}{x} =1\\14x-15x+30 = x^2-2x\\x^2-x-30=-0\\x=6](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7Bx-2%7D%20-%5Cfrac%7B15%7D%7Bx%7D%20%3D1%5C%5C14x-15x%2B30%20%3D%20x%5E2-2x%5C%5Cx%5E2-x-30%3D-0%5C%5Cx%3D6)
x cannot be negative
so x = 6 hours
i.e. Speed of Savanna is 50 mph and speed of
Tony is 70 mph
Time taken for Savanna to travel 300 miles is 6 hrs while for Tony to travel 280 miles is 4 hours.
