Beth is buying a new washing machine that
Mazyrski [523]

Beth will pay $ 405.45 for washing machine

<em><u>Solution:</u></em>

Given that, Beth is buying a new washing machine that  costs $450

Cost price = $ 450

She has a 15% off coupon

So, she has a discount of 15 % of 450

<em><u>Let us find the discount rate</u></em>

Discount rate = 15 % of 450

Discount\ rate = 15 \% \times 450\\\\Discount\ rate = \frac{15}{100} \times 450 = 0.15 \times 450 = 67.5

Thus discount rate is $ 67.5

<em><u>Therefore, sales price is given as:</u></em>

sales price = cost price - discount rate

sales price = 450 - 67.5 = 382.5

Thus she pays $ 382.5

Now she must pay 6 % sales tax

Let us find the sales tax rate

Sales tax rate = 6 % of 382.5

sales\ tax\ rate = 6 \% \times 382.5\\\\sales\ tax\ rate = \frac{6}{100} \times 382.5 = 0.06 \times 382.5 = 22.95

Thus sales tax rate = $ 22.95

<em><u>How much will Beth pay  for the washing machine?</u></em>

Total amount paid by Beth = sales price + sales tax rate

Total amount paid by Beth = 382.5 + 22.95 = 405.45

Thus Beth will pay $ 405.45 for washing machine
