If a phone company charges

0.35
$0.35 for the first minute and

0.30
$0.30 for each additional minute for a long-distance call, how long did you talk if the phone call cost
$
8.75
To find out how long the call lasted, we can set up an equation based on the charges given. Let's assume the call lasted for 'x' minutes.
We are given that the phone company charges $0.35 for the first minute and $0.30 for each additional minute. So, the cost for the first minute is $0.35, and for the remaining (x - 1) minutes, the cost is $0.30 multiplied by (x - 1).
The total cost of the call is given as $8.75. So, we can write the equation:
$0.35 + $0.30(x - 1) = $8.75
To solve this equation, we can simplify and isolate the variable:
$0.35 + $0.30x - $0.30 = $8.75
$0.30x = $8.75 - $0.35 + $0.30
$0.30x = $8.70
Now, we can divide both sides of the equation by $0.30 to solve for 'x':
x = $8.70 / $0.30
Calculating this, we find:
x ≈ 29
Therefore, the call lasted for approximately 29 minutes.
8.75=0.3x+0.35
x=minutes
Do the rest mate.
