To estimate the total cost to the nearest dollar, follow these detailed steps:
1. List the Given Amounts:
We have four dollar amounts:
- [tex]$23.45
- $[/tex]3.98
- [tex]$16.66
- $[/tex]12.08
2. Calculate the Total Sum of All Amounts:
Add up the amounts:
[tex]\[
23.45 + 3.98 + 16.66 + 12.08 = 56.17
\][/tex]
3. Round the Total Sum to the Nearest Dollar:
Look at the total sum calculated above, which is [tex]$56.17. The process of rounding involves looking at the first digit after the decimal point.
- If the digit is 5 or more, round up.
- If the digit is 4 or less, round down.
In this case, 56.17 has a 1 in the tenths place, which is less than 5, so we round down.
Therefore, rounding $[/tex]56.17 to the nearest dollar gives us $56.
4. Final Answer:
The estimated total cost to the nearest dollar is:
[tex]\[
\boxed{56}
