Answer:
1.668x10^13
Step-by-step explanation:
Lets say the final price of the bike is SP plus 13% VAT. So:
1.13 * SP = 6356.25
SP = 5625
Now SP was after 10% discount on Original Price, say MP. So:
0.9 * MP = 5625
MP = 6250
Therefore, the percent of Marked Price above Cost Price is:
(6250 - 5000) * 100/5000 = 25%
Answer: 54 feet or 648 inches.
Step-by-step explanation:
1. You know that 1 inch on the doll house corresponds to 1/2 foot for life-sized objects. Therefore, you can calculate the width of the full-sized house that it's modeled after, as following:

2. Then, the width in feet is: 54 feet.
3. And the width in inches is:
(Keeping on mind that 1 feet=12 inches)

Answer:
1 hour
Step-by-step explanation:
Let's assume that Patrick is travelling on a straight line throughout the whole path in order to minimize the distance.
The number of miles that he can travel on a full tank is:

The distance travelled by Patrick in one hour (from 2p.m. to 3p.m.) is:

If he is travelling at 10 miles per hour, and he could travel for a total of 20 miles, then the time remaining before the tank runs out of gasoline is:

If he continues at this rate, the gas will last for 1 more hour.
