Five months
Reason: graph y=35.75x+75 and y=17.95x+164 and they connect in the middle of 253-254 for month 5
My answers are in the picture above.
Answer:
26.88
Step-by-step explanation:
20%*22.40=4.48
22.40+4.48=26.88
The 15 lbs at $7=$105
So multiple 5x9 as a test and check results. 105-45=60
Here you can see that 60 is a factor of 6 by 10 so you got lucky and got the answer of 10lbs at $6 & 5lbs at $9=15 lbs at $7 average
