Answer:
The right choice is option B.
A total of 36 pizzas had vegetable toppings.
Step-by-step explanation:
Let x represent the number of pizzas.
According to the details:
On Saturday, the ratio of pizzas with meat to those with vegetables was 4:3.
The ratio for meat-topped pizzas is 4: 3
So;
The quantity of meat-topped pizzas = 4x
and
The quantity of vegetable-topped pizzas = 3x
We also know that the total number of pizzas made that day was 84.

Replacing the values gives us;

Combining similar terms yields;

When both sides are divided by 7, we find;
12 = x
The pizzas with vegetable toppings = 3x = 3(12) = 36
Consequently, there were 36 pizzas topped with vegetables.
