Answer:
12
Step-by-step explanation:
36 divided by 3 =12 for 1 teacher
Let small cups = S
Large cups = L
They bought a total of 8 cups, so S + L = 8
Rewrite as S = 8-L (1st equation)
Then you also have
$3S + $5L = $30 (2nd equation)
Replace the S in the second equation with the first equation:
$3(8-L) + $5L = $30
Simplify:
24 - 3L + 5L = 30
Combine like terms:
24+2L = 30
Subtract 24 from both sides:
2L = 6
Divide both sides by 2:
L = 3
They bought 3 large cups
Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)
Large = 3 cups, Small = 5 cups
Answer:
There are no solutions.
Step-by-step explanation:
When you solve for x in the first equation, you get x = (-1-y)/6. Plugging this value for x into the second equation gives you -4y = 4 + y, which has no solutions.
