Answer:

Step-by-step explanation:

You;ll run into this formula a lot. Make sure you study it carefully.

A = 25

a = 5

d = 13

Find n

25 = 5 + 13*(n- 1)

20 = 13(n - 1)

This isn't going to work out. 20/13 does not give a whole number which it should.

Answer: Tito is correct.

Step-by-step explanation:

According to the question,

Total part of pizza = 1 part of cheese pizza + 1 part of mushroom pizza + 1 part of pepperoni pizza = 3 part of a pizza

Part of pizza is eaten by Tito = $\frac{1}{4} + \frac{3}{8} + \frac{1}{2}=\frac{13}{8}$

Part of pizza is eaten by Luis = $\frac{5}{8} + \frac{1}{2} = \frac{9}{8}$

Since, $\frac{13}{8}$ part of 3 = $\frac{39}{8}$

And, $\frac{9}{8}$ part of 3 = $\frac{27}{8}$

But, $\frac{39}{8}$ > $\frac{27}{8}$

⇒ Tito ate more part of pizza than Luis.

If Tito did not eat pepperoni pizza then his part would be $\frac{3}{4}$ which is less than that of Luis.

Therefore, Tito ate more pizza than that of Luis because he ate pepperoni pizza.

Thus, Tito is correct.
