Answer:

Option 3. In step 3, she did not subtract one x from the left side

Step-by-step explanation:

we have the repeating decimal

0.272727...

Convert to fraction number

step 1

Let

x=0.272727...

step 2

Multiply by 100

100x=27.272727...

step 3

Subtract x from 100x

100x-x=27

99x=27

step 4

Find the value of x

x=27/99

therefore

Manda's work is not correct

In step 3, she did not subtract one x from the left side

Art [367]

Answer:

The total cost is $81.78

Step-by-step explanation:

First lets calculate the tip

tip = cost * percent of tip

tip = 65.42*.25

tip = 16.355

Which rounds to 16.36  since we are working with money and round to the nearest cent

total cost = cost of cut and blowout + tip

                = 65.42 +16.36

                     =81.78
