Answer:
p = -0.05m + 22
Step-by-step explanation:
As given in question,
The relation between the price and demand can be given by,
where is p is price and x is demand.
Since in order to sell 300 cards the price has to be fix at $7.
So,
7 = 300m+b <u> </u> (1)
And for every additional card they need to drop the price by $0.05.
So,
7-0.05 = 301m+b
=>6.95 = 301m + b<u> </u> (2)
Subtracting equation (1) from equation (2), we will have
6.95 - 7 = 301m - 300m
=>m = -0.05
By putting the value of m in equation (1), we get
7 = 300.(-0.05)+b
=> b = 22
So, the linear equation that show the relation between price and demand is given by
p = -0.05m + 22
Simple. one sixth of an hour is 10 minutes. so she can run half a mile in 10 minutes. by doing simple multiplication, you can tell she can run <u>3</u><u> </u><u>miles</u> exact in one hour if she was to keep that pace the whole time. The rate or speed eould be <u>3</u><u> </u><u>miles</u><u> </u><u>per</u><u> </u><u>hour</u><u>,</u> also written as <u>3mph</u><u>.</u>
