Find hour rate for 7 hours:
-----------------------------------------
Hourly charge = $3
Hourly charges for 7 hours = 3 x 7 = $21
-----------------------------------------
Find fixed charge :
-----------------------------------------
$33-21 = $12
There is a $12 fixed rental charge.
-----------------------------------------
Form Equation:
-----------------------------------------
Let the number of hours be x.
Total cost = 12 + 3x
-----------------------------------------
Answer: Total cost = 12+ 3x
-----------------------------------------
The number represented by it would be
1.09

Step-by-step explanation:
Answer:
its D
Step-by-step explanation:
C= n d
Answer:
d(n) = 85 * ( 3 - n )
Step-by-step explanation:
Let's find the common difference of the terms (if any).
The common difference is = 85 - 170 = 0 - 85 = -85 - 0 = -85
For an arithmatic sequence with first term a, common difference d,
nth term = a + ( n - 1 ) * d
So, d(n) = 170 + ( n - 1 ) * (-85)
= 255 - 85n
= 85 ( 3 - n )
