About 26% of all bicycles in the United States have off-road tires. Juan surveys a random sample of bicycles from two towns. Com
Nesterboy [21]

According to the information provided by the graph, it can be inferred that in town A there is a lower percentage (20%) than the national percentage of bicycles with off-road wheels, while in town B the percentage is higher (45%).

<h3>How to calculate the percentage of bicycles with off road wheels in each town?</h3>

To calculate the percentage of bicycles with off-road wheels in each town, we must perform the following mathematical operation.

First we must add the number of bicycles of each type to know the total number of bicycles in the town:

  • Town A: 3 + 12 = 15 bikes
  • Town B: 9 + 11 = 20 bikes

Now we must calculate what percentage is equivalent to 3 bicycles with off-road wheels from town A and what percentage is equivalent to 9 bicycles with off-road wheels from town B.

15 ÷ 100 = 0.15

0.15 × 20 = 3

So, 3 bicycles with off-road wheels from town A are equivalent to 20% of the total number of bicycles.

  • 20 ÷ 100 = 0.2
  • 0.2 × 45% = 9

Then the 9 bicycles with off-road wheels in town B are equivalent to 45% of the total number of bicycles.

According to the above, 20% of the bicycles in town A have off-road wheels, while 45% of the bicycles in town B have off-road wheels.
