Answer 1

30℅ of 10 is 3 so 3 pizzas have 12 slices. 3 x 12= 36. 70% of of 10 is 7 so 7 pizzas have 8 slices. 8 x 7=56. So 36+56=92. There are 92 slices of pizza.

Answer 2

Kelly has 10 pizzas in all. 30% of them (which is 3 pizzas) have 12 slices. 3 pizzas with 12 slices each is 36 slices. 70% of the pizzas (which is 7 pizzas) have 8 slices each. 7 pizzas with 8 slices each is 56 slices of pizza. 36+56= 92 slices.
