a restaurant offered pizza with 3 types of crust and 7 different toppings. how many different types of pizzas could be offered. 7 toppings on each i came up with 21 but not sure
That is assuming that only one topping can be used on any pizza. If that is true, you are right.
To calculate the total number of different types of pizzas that could be offered, you need to multiply the number of options for crust by the number of options for toppings.
In this case, there are 3 types of crust and 7 different toppings.
So the total number of different types of pizzas would be:
3 (crust options) * 7 (toppings options) = 21
Therefore, there would be a total of 21 different types of pizzas that could be offered.
To find the total number of different types of pizzas that can be offered, you need to multiply the number of crust options by the number of topping options.
In this case, there are 3 types of crust and 7 different toppings.
To find the total number of pizza options, you would multiply these numbers together:
3 (number of crust options) * 7 (number of topping options) = 21.
So, your initial calculation of 21 is correct. The restaurant could offer a total of 21 different types of pizzas with 3 types of crust and 7 different toppings.
