Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-8</u></em></h2>

Step-by-step explanation:

3(1.5x + 9)= -9

=> 4.5x + 27 = -9

=> 4.5x = -9-27

=> 4.5x = -36

=  >  \frac{45x}{10}  =  - 36

=  >  x =  - 36 \times  \frac{10}{45}

=  > x =  - 4 \times  \frac{10}{5}

=> x = -4 × 2

=> <em><u>x = </u></em><em><u>-8</u></em><em><u> (Ans)</u></em>

Answer:

x = -8

Step-by-step explanation:

3(1.5x + 9) = -9

Divide both sides by 3

1.5x + 9 = -3

Subtract 9 from both sides

1.5x = -12

Divide both sides by 1.5

x = -8

1. Kane earns an annual salary of $42,500.
Katarina [22]

Answer:

$1753.13

Step-by-step explanation:

Kane's Annual Salary  = $42,500

A customer buys a different book that has an original selling price of $38. The book is discounted 25%. The customer must pay a
Marina CMI [18]

Answer:

$30.21

Step-by-step explanation:

100% -25%= 75%

Discounted price of the book

= 75% ×$38

= $28.50

Since the customer must pay an additional 6% of the discounted price,

percentage of discounted price paid

= 100% +6%

= 106%

Total amount paid

= 106% × $28.50

= $30.21

_________________________________

Alternative working:

Original selling price= $38

Since the book is discounted 25%,

100% ----- $38

1% ----- $0.38

75% ----- 75 ×$0.38= $28.50

Since the sales tax is based on the discounted price, we let the discounted price be 100%.

100% ----- $28.50

1% ----- $0.285

106% ----- 106 ×$0.285= $30.21

∴ The total amount the customer pays for the discounted book is $30.21.
