Lena does not have enough cheese to make 2 batches of Mac and cheese and 3 pizzas.
Step-by-step explanation:
<u>Number of ounces of cheese required to make 2 batches of Mac and cheese </u>
1 batch of Mac and Cheese requires 6 ounces of cheese,
Therefore,
2 batches of Mac and cheese requires = 
=12 ounces of cheese
<u>Number of ounces of cheese required to make 3 pizzas</u>
2 pizzas needs 16 ounces of cheese.
That means 1 pizza needs 8 ounces of cheese.
Therefore,
3 pizzas need =
ounces of cheese
=24 ounces of cheese
<u>Total ounces of cheese she needs for the event </u>
Cheese required to make 2 batches of Mac and cheese + Cheese required to make 3 pizzas
=12 ounces + 24 ounces
