To fill in the empty values in the table, we need to first analyze the existing data and calculate the missing amounts.
Data from the table:
- Number of Cars Washed: 5, Total Amount Raised: $7
- Number of Cars Washed: 7, Total Amount Raised: $231
- Number of Cars Washed: 18, Total Amount Raised: $319
- Number of Cars Washed: 24, Total Amount Raised: ?
- Number of Cars Washed: 30, Total Amount Raised: ?
From the data we have:
- The raise for washing cars can be calculated.
- Let's find the amount raised per car washed for known entries:
- For 7 cars washed: $231 \[ \text{Amount per car} = \frac{231}{7} = 33. \]
- For 18 cars washed: $319 \[ \text{Amount per car} = \frac{319}{18} \approx 17.72. \]
Given that the amounts raised per car seems to differ significantly, let's assume a linear growth based on the entries.
-
First calculate for 24 cars: If we assume a steady increase between known values, we could estimate the total for 24 cars.
Using the established amounts:
- 7 cars: $231
- 18 cars: $319
The increase from 7 to 18 cars is: \[ $319 - $231 = $88, \] which is for 11 cars. Thus, \[ \text{Increase per car} = \frac{88}{11} = 8. \]
So for the cars:
- 7 cars: $231 + (24 - 7) \times 8 = 231 + 136 = 367.
- Next, calculate for 30 cars based on 24: Continuing the increase,
- 24 cars: $367
- From 24 to 30 cars means 6 more. \[ $367 + (30 - 24) \times 8 = 367 + 48 = 415. \]
- Now filling the table:
| Number of Cars Washed | Total Amount Raised | |-----------------------|--------------------| | 5 | $7 | | 7 | $231 | | 18 | $319 | | 24 | $367 | | 30 | $415 |
Now, the table is complete, with all values filled.
