Answer:
T(x) = 88 + 12x
Step-by-step explanation:
Givens:
1st hour = 100 copies
subsequent hours s(x) = 12( x - 1), where x is number of hours
Let total sales be represented by T(x)
Total sales, T(x)
= sales in first hour + sales in subsequent hours
= 100 + 12 (x - 1)
= 100 + 12x - 12
= 88 + 12x
Answer: Total sales function is [tex]S(x)=88+12x[/tex]
Step-by-step explanation:
Since we have given that
Number of copies the first hour he sell at a local game = 100
Sales function is expressed as
[tex]s(x)=12(x-1)=12x-12[/tex]
so, function that shows total sales including the first hour is given by
[tex]S(x)=100+s(x)\\\\S(x)=100+12x-12\\\\S(x)=88+12x[/tex]
Hence, total sales function is [tex]S(x)=88+12x[/tex]
