Answer:
Please see the attachment for double number line.
Explanation:
We are given cost of 4 water bottles is $10
We can write ,
Cost of 4 bottles = $10
Cost of 1 bottle = $2.5
Cost of 2 bottles =$5
Cost of 3 bottles =
= $7.5
Cost of n bottles = $2.5n
Now we draw the double number line.
Bottom line(Line 1) will take as number of bottles:
1 2 3 4 5 6
Above line (Line 2) will show the cost of corresponding number of bottles:
2.5 5 7.5 10 12.5 15
Answer:
3) 7:8 7 to 8 4) 40/100 = 2/5 5) 60 mph 6) 300 kph 7) Jane 8) Jon can go faster
Step-by-step explanation:
5) 120/2 =60
6) 900/3 =300
7) Tim =50/5= $10 an hour
Jane= 24/2 =$12 an hour
