Answer:

  • Each large pizza feeds about 5 people and each small pizza feeds about 1 person.

Explanation:

Let's say L for 'Large pizza' and S for 'Small pizza'.

We know that:

  • Last week = 3S + 2L = 13 players
  • This week = 3S + 4L = 23 players

Work:

  • 3S + 2L = 13

3S + 4L = 23

  • -2L = 13 - 23
  • => -2L = -10
  • => 2L = 10
  • => L = 5

Now, let's substitute the value of L into the first equation.

  • 3S + 2L = 13
  • => 3S + 2(5) = 13
  • => 3S + 10 = 13
  • => 3S = 13 - 10
  • => 3S = 3
  • => S = 1

Hence, each large pizza feeds about 5 people and each small pizza feeds about 1 person.

Hoped this helped.
