Final answer:
Charlie spent a total of $275 on a jar of spaghetti sauce, a package of spaghetti noodles, and a third item at the factory store.
Step-by-step explanation:
To calculate the total amount spent by Charlie on the three items at the factory store, we simply need to add up the cost of each item. Charlie bought a jar of spaghetti sauce for $249, a package of spaghetti noodles for $15, and a third unknown item at a till for $11. The total amount spent would be:
$249 (spaghetti sauce) + $15 (spaghetti noodles) + $11 (till item) = $275.
Therefore, Charlie spent $275 on the three items altogether.
