Answer:
60
Step-by-step explanation: 12L + 1/2 = 72.5
72.5 - 24 - 8.5 + 20
72.5 -24 = 48.5 - 8.5 = 40
40 + 20 = 60
Answer:
y ≤ q 0 or y ≥ 16.
Step-by-step explanation:
Rearrange unknown terms to the left side of the equation: |y - 8| ≥ q 19
- y=x+2.....(1)
- y+1= – 4x......(2)
Put value of y in Equation 1 in Equation 2.
Let's find value of y :
Solution:
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.
