Shawn invites some friends over for pizza and a movie. He makes a small cheese pizza for himself and a large pepperoni pizza for his friends. Shawn uses 0.75 pounds of dough for the cheese pizza and twice as much dough for the pepperoni pizza. How much dough does Shawn use in all?
Write your answer as a whole number or decimal.
.75 + 2*.75 = 3*.75 = ___
3/4 + 2 * 3/4 = 3/4 + 6/4 = ___
To find out how much dough Shawn uses in total, we need to calculate how much dough he uses for each pizza and then add them together.
We know that Shawn uses 0.75 pounds of dough for the cheese pizza.
Now, we need to find out how much dough he uses for the pepperoni pizza. The pepperoni pizza uses twice as much dough as the cheese pizza. So, we can calculate it by multiplying the dough for the cheese pizza by 2.
0.75 pounds of dough * 2 = 1.5 pounds of dough
Therefore, Shawn uses 1.5 pounds of dough for the pepperoni pizza.
To find the total amount of dough used, we add the dough for the cheese pizza and the dough for the pepperoni pizza together.
0.75 pounds of dough + 1.5 pounds of dough = 2.25 pounds of dough
Therefore, Shawn uses a total of 2.25 pounds of dough.
