The companies being considered are:
The company that is concerned with corded telephones
The company that is concerned with cellphones
Let x represent the number of years since 2002 and y represent the total number of accounts
From the information given,
Considering the first company,
Initial number of accounts = 946 x 10^6
The number of accounts fell by approximately 28 million per year. This means that in x years, the number of accounts that would have been lost is
28 x 10^6 * x
= - 28x x 10^6
It is negative because it is reducing
The slope intercept form of a linear equation is expressed as
y = mx + c
where
m = rate of change
c = y intercept of value of y when x = 0
By comparing with the given scenario,
Answer: 24 band posters should be sold
Step-by-step explanation:
First take the expression down to its simplest form;
= 5:4
Assume she sells 30 movie posters, her movies posters drop to;
= 100 - 30
= 70 movie posters
We need a number of band posters remaining that will give a ratio of 5:4 with movie posters.
In fraction form, the number of movie posters is;
= 5/9 because 9 would be the total number of both movie posters and band posters.
Create an expression to find the total number of posters if 70 are movie posters;
5/9x = 70
x = 70 ÷ 5/9
x = 126 posters
Number of band posters that should be left are;
= 126 - 70
= 56
Number of band posters that should be sold;
= 80 - 56
= 24 posters
<em>The new ratio would be 70:56.</em>
Answer:
C(t) = I/F [1 - e^(-Ft/V) ] + C₀e^(-Ft/V)
as t = 0 ; C(t) = 1/F
Explanation:
