Eckhart School is selling candy to raise money for its sports programs. Last year the school raised $480 during a 12-day fundraiser. The school expects this year's daily sales to be in proportion to last year's daily sales. Based on the school's expectations, which of the following statements is correct?
A.
In 3 days, the school will raise $120.
B.
In 7 days, the school will raise $240.
C.
In 13 days, the school will raise $500.
D.
In 22 days, the school will raise $960.
B. In 7 days, the school will raise $240.
Since the school raised $480 in 12 days, their average daily sales were $40 ($480 divided by 12). Assuming that this year's daily sales will be in proportion to last year's daily sales, we can calculate:
- In 3 days, the school would raise 3 x $40 = $120.
- In 7 days, the school would raise 7 x $40 = $280.
- In 13 days, the school would raise 13 x $40 = $520.
- In 22 days, the school would raise 22 x $40 = $880.
Therefore, the correct statement is B. In 7 days, the school will raise $240.
To find the answer, we need to determine the amount of money the school raises in a single day, and then apply that to the given time frame.
Given that the school raised $480 over 12 days, we can find the daily sales by dividing $480 by 12:
$480 ÷ 12 = $40.
Therefore, the school is expected to raise $40 each day.
Now, let's apply this to the options:
A. In 3 days, the school will raise $120.
To calculate this, we multiply $40 (daily sales) by 3 (number of days):
$40 × 3 = $120.
B. In 7 days, the school will raise $240.
Following the same calculation, we have:
$40 × 7 = $280.
C. In 13 days, the school will raise $500.
Again, applying the multiplication:
$40 × 13 = $520.
D. In 22 days, the school will raise $960.
Once more, calculating the total:
$40 × 22 = $880.
Based on the calculations:
A. In 3 days, the school will raise $120. (Correct)
B. In 7 days, the school will raise $280.
C. In 13 days, the school will raise $520.
D. In 22 days, the school will raise $880.
Thus, the correct statement is A. In 3 days, the school will raise $120.
To determine the correct statement, we can use the information given in the question. Last year, the school raised $480 in total over 12 days. This means they raised an average of $480/12 = $40 per day.
Since the school expects this year's daily sales to be in proportion to last year's daily sales, we can calculate the expected amount raised for different numbers of days.
A. In 3 days, the expected amount raised would be 3 * $40 = $120.
B. In 7 days, the expected amount raised would be 7 * $40 = $280.
C. In 13 days, the expected amount raised would be 13 * $40 = $520.
D. In 22 days, the expected amount raised would be 22 * $40 = $880.
Therefore, the correct statement is B. In 7 days, the school will raise $240.
