Answer:
At first instance, they can eat 3 SMALL pizzas together, while the total number of pizzas they can eat if there are subsequent instances is
3 × (Number of instance)
Step-by-step explanation:
Here, we have a word math problem, with Joey and his 2 friends who can eat the same amount as him
That is if the amount Joey can eat is x then each of his two friends can eat x hence total amount Joey and the two friends can eat is
x + 2x = 3x,
Where x is an number eaten per person at an instant
Therefore, if they decide to order all SMALL pizzas, the number of pizzas they can eat at the first instant is 3 × 1 = 3 SMALL pizzas
at subsequent instance, the number of pizzas eaten in total is 3·x pizzas.
