39 times 3 and 15 times 3 then 27 times 2 then add together to get 216
Just plug in the numbers into the equation.
m = 4a + 2c
a = adults
c = children
m = meatballs
The information given says there are 25 adults and 5 children. So now:
a = 25
and
c = 5
in the equation m = 4a + 2c
Now plug in the values.
m = 4(25) + 2(5)
m = 100 + 10
m = 110
This means that 110 meatballs are required for 25 adults and 5 children.

fill the dot for including equality
point to left for "smaller than"
I would believe it to be option 2 Because (m) will be meals but for it to be less would be 500+15m>1000+5m
