Parents will allow you to stream videos on your tablet if you agree to prepay the monthly bill. If the initial charge to set up an account is $50 and the monthly fee is $18, create a table that would represent the cost each month for the first year.
Every Month $68 $18 $18 $18 $18 $18 $18 $18 $18 $18 $18 $18
<span>Total For Year$68 $86 $104 $122 $140 $158 $176 $194 $212 $230 $248 $266 </span>
300 messages would have to be sent or received in order for the plan to cost same each month.
Step-by-step explanation:
Given,
Cost per month = $30
Per text sent or received charges = $0.10
Let,
x be the number of texts sent or received.
A(x) = 0.10x+30
A comparable plan costs = $60 per month
Text messages are unlimited.
B(x) = 60
For the two plans to cost equal;
A(x) = B(x)
![0.10x+30=60\\0.10x=60-30\\0.10x=30](https://tex.z-dn.net/?f=0.10x%2B30%3D60%5C%5C0.10x%3D60-30%5C%5C0.10x%3D30)
Dividing both sides by 0.10
![\frac{0.10x}{0.10}=\frac{30}{0.10}\\x=300](https://tex.z-dn.net/?f=%5Cfrac%7B0.10x%7D%7B0.10%7D%3D%5Cfrac%7B30%7D%7B0.10%7D%5C%5Cx%3D300)
300 messages would have to be sent or received in order for the plan to cost same each month.
