Answer:
87 minutes
Step-by-step explanation:
Let the total number of minutes = m
Our equation is given as:
$20.21 = $14.99 + 0.06m
20.21 = 14.99 + 0.06m
Collect like terms
0.06m= 20.21 - 14.99
0.06m = 5.22
m = 5.22/0.06
m = 87
Therefore, the total number rod minutes used is 87 minutes
Answer:
--- the equation of SaveMore company
Step-by-step explanation:
Given
SaveMore
Required
Determine the equation
Let
So, we have:
The equation for the second company is not given. So, the (b) part cannot be correctly answered.
A general solution to the (b) part is:
Assume the equation is:
Next, we equate both
i.e.
This gives:
Collect like terms
Divide by 0.2
<em>Hence, the charges will be the same after 30 texts</em>
you need to find the average
so 2 +4=6
6/2 =3 points
