Answer: $51.00
Step-by-step explanation:
Since $0.20 is charged per minutes , that is , the amount charged for 300 minutes will be :
300 x 0.20 = $60
Her monthly cell phone plan charges a flat monthly fee of $25.00 , that is the total amount charged will be
$60 + $25
= $85
There is a 40% discount , then we have
40% of $85
= $34
So, the amount of her first cell phone bill = $85 - $34
= $51.00
first you put this equation into y=mx+b form then you look at the slope of the equation. if both of the slopes are same then its parallel.
I think the answer is: 5 x (12-9) = 15
