Ms. Trowbridge will receive a 40% discount off her first cell phone bill. Her monthly cell phone plan charges a flat monthly fee
Sholpan [36]

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

The table shows the steps for solving the given inequality for x.
slavikrds [6]

Given inequality -3(4-6x) < x+5.

We have -3 in front of Parenthesis.

That represents multiplication of -3 and Parenthesis.

The multiplication of Parenthesis could be done by applying distributive property.

On distributing, we get

-12+18x < x+5

x is added on right side of the inequality. The reverse operation of addition is subtraction. So we need to subtract x from both sides, we get

-12+18x-x < x-x+5

-12+17x < 5

Now, we need to get rid -12 from left side.

So, we need to apply addition property of equality, we need to add 12 on both sides, we get

-12+12+18x < x+5+12

17x < 17

We need to get rid 17 from left side. So we need to apply division property of equality.

On dividing both sides by 17, we get

17x/17 < 17/17

x<1.
