100 + 70 = 170
170 / 10 = 17

Answer:
134
Step-by-step explanation:
to find how many gifts it can make, you must find how many times 34 can go into 4580. do this by deciding 4580 by 34.
4580/34=134.7
Since you can't make less than a whole gift you must round it down to 134
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2
<em>The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.</em>
Add 145, 156, 210. and 255 then divide by 4. The mean equals 184.
