Answer:
They sold 175 small popcorns and 103 Large popcorns
Step-by-step explanation:
The equation is
L + S = 278 this means the total large and small popcorn that they sold is 278
3L+1S= 484 The owner of the question told me the total profit is 484
When we solve we can turn the first equation into L=-S+278
we substitute L=-S+278 into 3L+1S=484 we get -3S+ 834+ S= 484
-3S+834+1S=484
-2S+ 834= 484
-2S=- 350
2s= 350
s= 175
We know that they sold 175 small popcorns now. Now we Substitute 175 into L+ S= 278 and get L+ 175=278
L+175=278
L= 103
They sold 175 small popcorns and 103 Large popcorns
