A charity receives a donation of $1,508 from 142 donors. How much will the charity expect to raise if there are a total of 250 donors?

To find out how much the charity will expect to raise with a total of 250 donors, we can use proportions.

First, let's find the average donation amount per donor in the initial scenario:
Average donation amount = Total donation amount / Number of donors
Average donation amount = $1,508 / 142
Average donation amount ≈ $10.63 (rounded to the nearest cent)

Now, let's calculate the total donation amount with 250 donors, using the average donation amount per donor:
Total donation amount = Average donation amount × Number of donors
Total donation amount = $10.63 × 250
Total donation amount = $2,657.50

Therefore, the charity can expect to raise approximately $2,657.50 with a total of 250 donors.
