42 students and 2 teachers are at a pizza party. 23 students want 2 pieces of pizza and the remaining students and teachers want 3 pieces. Each pizza has 8 pieces. How many pizzas should they order?
pieces = (23 * 2) + [(42 + 2 - 23) * 3]
divide "pieces" by 8 to find "pizzas" ... remember to round UP if necessary

BEES
To determine the number of pizzas they should order, we first need to calculate the total number of pieces of pizza required.
Let's calculate the number of pieces needed for the 23 students who want 2 pieces each:
23 students * 2 pieces per student = 46 pieces.
Next, let's calculate the number of pieces needed for the remaining students and teachers who want 3 pieces each:
(42 students + 2 teachers - 23 students) * 3 pieces per person = 63 pieces.
Now, let's add up the total number of pieces needed:
46 pieces + 63 pieces = 109 pieces.
Since each pizza has 8 pieces, we can now find out how many pizzas they should order by dividing the total number of pieces by the number of pieces per pizza:
109 pieces / 8 pieces per pizza = 13.625 pizzas.
Since we cannot order a fractional amount of pizzas, we need to round it up to the nearest whole number. Therefore, they should order 14 pizzas to ensure everyone gets enough slices.
