Answer:
Your answer will be C. $5.79.
Step-by-step explanation:
To get this answer, you have to take the original price (3.99) and multiply it by the mark up (45%)
3.99x0.45=1.79
Then, you add 3.99 and 1.79 to get your final answer.
3.99 + 1.79 = 5.78
The answer is off by one penny, BUT, it's tricky to get it exact when you're working with decimals and percentages.
Answer:
So her average speed for the entire trip is 30 mph (miles per hour).
Step-by-step explanation:
Use distance = rate x time
18 minutes is 3/10 of an hour.
So the distance to the store is:
d = 20*(3/10) = 6 miles
The distance downhill is the same, 6 miles. So:
6 = (60)t
6/60 = t
1/10 = t
Where t is the time it took to go back home. So t is .1 hour (6 minutes).
To calculate average speed we use the formula:
average speed = total distance/ total time
average speed = (6+6)/(.3 + .1) = 12/(.4) = 30
So her average speed for the entire trip is 30 mph (miles per hour).
