Beth is buying a new washing machine that
costs $450. she has a 15% off coupon and
must pay 6% sales tax. how much will beth pay
for the washing machine?

Beth will pay $ 405.45 for washing machine

Solution:

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

Let us find the discount rate

Discount rate = 15 % of 450

Thus discount rate is $ 67.5

Therefore, sales price is given as:

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

Thus sales tax rate = $ 22.95

How much will Beth pay  for the washing machine?

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
