Final answer:

To find the number of egg sandwiches Lillian makes, subtract the number of tuna and ham sandwiches from the total. 25% of 480 are tuna sandwiches and 45% are ham sandwiches. Subtracting these from the total gives you the number of egg sandwiches.

Step-by-step explanation:

To find the number of egg sandwiches that Lillian makes, we need to subtract the number of tuna and ham sandwiches from the total number of sandwiches she makes.

First, we find 25% of 480 to find the number of tuna sandwiches: 25% of 480 = 0.25 * 480 = 120.

Next, we find 45% of 480 to find the number of ham sandwiches: 45% of 480 = 0.45 * 480 = 216.

Finally, we subtract the number of tuna and ham sandwiches from the total number of sandwiches to find the number of egg sandwiches: 480 - 120 - 216 = 144.

Answer:

144 egg sandwiches

Step-by-step explanation:


25\% + 45\% = 70\%, and
100\% - 70\% = 30\%. Thus,
30\% of the
480 sandwiches are egg sandwiches. Since "of" means multiply, we have
30\% \cdot 480. We know
30\% = (30)/(100) = (3)/(10), so we can rewrite it as
(3)/(10) \cdot 480. We cancel
480 with
10 which is
480 / 10 = 48. We multiply
48 by the numerator,
3, to get
48 \cdot 3 = 144. Thus, Lillian makes
\boxed{144 \text{ egg sandwiches.}}
