Sure, let's break down the problem and find out how much Charlle spent on these three items.
First, we need to consider the individual prices of each item:
- A jar of spaghetti sauce costs \[tex]$2.49.
- A package of spaghetti noodles costs \$[/tex]1.58.
- A gallon of milk costs \[tex]$3.17.
To find the total amount spent, we need to add these three amounts together:
1. Start by adding the cost of the spaghetti sauce and the spaghetti noodles:
\[
2.49 + 1.58 = 4.07
\]
2. Next, add the cost of the gallon of milk to the previous sum:
\[
4.07 + 3.17 = 7.24
\]
Therefore, the total amount spent by Charlle on these items is:
\[
\boxed{7.24}
\]
Thus, the correct answer is:
\[
\$[/tex]7.24
\]
