The table shows the amount earned for washing cars. How much is earned for washing 25 cars? 3 cars=$13.50, 6 cars=$27, 9 cars=$40.50, and 12 cars=$54
To find out how much is earned for washing 25 cars, we need to determine the pattern from the given information.
From the table, we can observe the following pattern:
- For every 3 cars, the amount earned increases by $13.50.
Using this pattern, we can calculate the amount earned for 25 cars as follows:
First, let's find out how many groups of 3 cars are there in 25 cars:
25 cars ÷ 3 cars/group ≈ 8 groups
Next, multiply the number of groups by the amount earned for each group:
8 groups × $13.50/group = $<<8*13.50=108>>108
Therefore, the amount earned for washing 25 cars is $108.
To find out how much is earned for washing 25 cars, we need to determine the pattern or relationship between the number of cars and the amount earned.
Looking at the provided data, we can observe that as the number of cars increases, the amount earned also increases. In this case, the relationship appears to be linear, meaning that the amount earned increases at a constant rate for each additional car.
To find the rate of increase, we can calculate the difference in the amount earned for consecutive numbers of cars:
Difference between earnings for 3 cars and 6 cars = $27 - $13.50 = $13.50
Difference between earnings for 6 cars and 9 cars = $40.50 - $27 = $13.50
Difference between earnings for 9 cars and 12 cars = $54 - $40.50 = $13.50
Since the difference in earnings is consistently $13.50, we can infer that for every additional 3 cars, the amount earned increases by $13.50.
Now, we can determine how many groups of 3 cars are needed to reach 25 cars:
25 cars / 3 cars = 8.33
Since we can't have a fraction of a car, we need to round up to the nearest whole number. Therefore, we need 9 groups of 3 cars to reach a total of 25 cars.
Finally, we can find the amount earned for washing 25 cars by multiplying the rate of increase ($13.50) by the number of groups of 3 cars (9):
Amount earned for washing 25 cars = $13.50 × 9 = $121.50
Therefore, the amount earned for washing 25 cars is $121.50.
54/12 = 4.50
25 * 4.50 = ?
looks like it costs $4.50 to wash one car
