Answer:
72 cans
Step-by-step explanation:
step 1
Find the number of people
we know that
She ordered 1 pizza for every 4 people
using proportion
Find out the number of people for 6 pizzas

step 2
Find the number of cans ordered
we know that
Charissa ordered 3 cans of lemonade for each person
so
using proportion
Find out the number of cans of lemonade she ordered for 24 people

X = 180 - 104 - 22 = 180 - 126 = 54 degrees
y = 180 - 54 = 126 degrees
z = 180 - 126 - 19 = 180 - 145 = 35 degrees
