gavmur [86]

Answer: m1 = 0.5

M2= 0.375

M3 = 2.25

M4 = 3.0

M5 = 13.5

M6 = 0.285

M7 = 7.0

Step-by-step explanation:

(20,40)-(15,30)=(5,10), m1=5/10=0.5

(18,48)-(12,32)=(6,16), m2=3/8=0.375

(72,32)-(27,12)=(45,20), m3=9/4=2.25

(60,20)-(45,15)=(15,5), m4=3.0

(243,18)-(27,2)=(216,16), m5=27/2=13.5

(24,84)-(18,63)=(6,21), m6=2/7=0.285...

(84,12)-(63,9)=(21,3), m7=7.0

A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol
mestny [16]
Let N be the number of items sold and p the price. 
Since the variation is inverse, then the relation between N and p is:
N=k\dfrac{1}{p}
For N=20000 and p = $9.5, we get the formula:
 20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000
If p = 8.75, then the number of items sold can be computed using the formula:
N= 190000\dfrac{1}{8.75}=21714 \text{ total items}
