Question

To determine an estimate for the cost of each window, divide the total cost of 5820 by the number of windows, which is 28. This gives us 207.857142857. Rounded to the nearest dollar, it would be 208. To find the cost of each window, rounded to the nearest dollar while leaving the remainder undivided, we can subtract the rounded estimate from the rounded-up estimate. 208 - 207 = ?

1) 1
2) 2
3) 3
4) 4

Answer 1

We determine the estimate for the cost of each window by dividing the total cost by the number of windows and rounding the result. The remainder after rounding the estimated cost to the nearest dollar is found to be 1 dollar.

Step-by-step explanation:

To determine the estimate for the cost of each window, we take the total cost of windows, which is 5820 dollars, and divide it by the number of windows (28). Doing the math, we get 5820 ÷ 28 = 207.857142857. When this number is rounded to the nearest dollar, it becomes 208 dollars. Now, to find the cost of each window rounded to the nearest dollar, leaving the remainder undivided, we subtract the rounded estimate (208 dollars) from the rounded-up estimate (207 dollars). This difference is:

208 - 207 = 1

This calculation tells us that the remainder we are interested in is 1 dollar, which represents the undivided portion after rounding the estimated cost of each window.
