Answer:
3600
Step-by-step explanation:
So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 55$ obviously. Secondly 45$ for the next 10 boxes.
So for now we can simply calculate that we have spent around 100$ which means 20 boxes. The remaining money left is 77$ so we can buy 77/3.5 = 22 only 22 boxes with that money. Hence a total of 42 boxes.
N x 2 = 12 + 5n
2n - 5n = 12
-3n = 12
3n = -12
n = -4
the anwser is
Step-by-step explanation:
the anwser is 5 kg
X/-3 = 12 + x
x = -36 - 3x
4x = 36
x= = 9
The number is 9.
