Answer:
0.07
dollar per minute
Step-by-step explanation:
Given the charging formula :
C(n) = 13 +0.07n
n = number of minutes talked, and
C(n) = monthly charge, in dollars
The slope is the change in amount charged per change in the number of minutes talked.
Also, from The slope intercept equation :
y = mx + c
Comparing the equation :
0.07n = mx
m = 0.07
Since, The slope is the change in amount charged per change in the number of minutes talked.
Amount charged in dollars, talk time measured in minutes ;
Unit = dollar per minute
Just find the surface area. 5*7=35, but 35*2=7<span>0</span>, because the top and bottom. Then do 7*3*2=42, for 2 parallel sides, and then 3*5*2=30. Now add 70+30+42=142 square inches. There's your answer.
Step-by-step explanation:
Divide your 320 million with 618 and that's your answer.
