Answer:
84+x*60=y
Step-by-step explanation:
you take the amount of people, and multiply it by thier fee, add the single time payment of 84$, and you have your answer which is, 564$
Distance from home to store = 4 * 0.5 = 2 miles.
Time taken to return home = (2/12) * 60 =10 minutes.
Total distance traveled = 2 * 2 = 4 miles.
Total time taken = 30 + 10 = 40 minutes.
Average speed for entire trip = total distance / total time in hours.
Answer:
77+24

Step-by-step explanation:
Since it is a square, the side lengths are the same. Multiply the side lengths by each other to find the area.
(4

I assume you are looking for the percent increase in which case you want to find the difference between original and new, then find the percentage of the original that gives you that difference... let me show you...
400 is the new value and 350 is the original value, so we have an increase of 400 - 350 = 50
So now we find what percentage of 350 is 50.
In math "of" means ×
"is" means =
x × 350 = 50
350x = 50
x = 50/350
x = .1429
multiply by 100 to convert to percent (move decimal to the right 2 places).
.1439 × 100 = 14.29%
So the percentage of increase is 14.29%
