<span> all of our square numbers from 1 to 80 are 1, 4, 9, 16, 25, 36, 49, 64. </span>
First answer is 4 chances and second answer is 2 chances
The equation is 4 meatballs for every adult and 3 for every child. Replace a and c and solve:
M = 4(20) + 2(8)
M = 80 + 16
M = 96
They need 96 meatballs.
Your answer is correct :)
