The average number of sales at a certain store for 4 consecutive days is 26. If the number of sales on the fifth day is 46, what is the average number of sales for the 5 days?
The average number of sales for the 5 days is 30.
To find the average sales over the five days, we first calculate the total sales for the first four days and then add the sales from the fifth day. The total sales for the first four days is 104 (4 days * 26 sales per day), and with the fifth day's sales at 46, the overall total becomes 150. Dividing this by 5 gives an average of 30.
An average of 36 would imply a total sales amount of 180 (36 * 5), which is incorrect. The total sales calculated from the problem is 150, making an average of 36 impossible for these five days.
This is the correct choice. The total sales for the five days is 150 (104 from the first four days and 46 from the fifth day), and dividing this total by 5 yields an average of 30 (150 / 5 = 30).
An average of 28 would suggest a total sales amount of 140 (28 * 5), which does not match the calculated total of 150. Therefore, this average is not applicable to the given sales data.
Choosing 27 would indicate a total sales amount of 135 (27 * 5), which again is lower than the total sales of 150 calculated from the first four days and the fifth day. This makes 27 an incorrect average.
The average number of sales for the five days is determined by first calculating the total sales and then dividing by the number of days. With the totals confirmed, the average sales for the five days is accurately found to be 30, while the other options (36, 28, and 27) do not align with the calculated total sales. This highlights the importance of calculating totals accurately before determining averages.
