Step-by-step explanation:
<u><em>The complete question is</em></u>
Tanisha and Rebecca are signing up for the new cellphone plans that only charge for the number of minutes and everything else is included in a monthly fee. Their plans are as follows:
Tanisha s Plan: $0.15 per minute used talking and a $25 monthly fee
Rebecca s Plan: $0.10 per minute used talking and a $18.50 monthly fee
After how many minutes will the two plans charge the same amount?
Let
x ----> the number of minutes
y ---> the total charge in dollars
we know that
<em>Tanisha s Plan</em>
-----> equation A
<em>
Rebecca s Plan</em>
-----> equation B
To find out after how many minutes will the two plans charge the same amount, equate equation A and equation B
solve for x

therefore
They will never pay the same amount , because the time cannot be a negative number.
Rebecca s Plan is better than Tanisha s Plan because it has smaller fee and less cost per minute
