28.An Amazon Echo originally costs $99.99. It is on sale for 10% off. Sales tax of 7.5% is then added to the sale price. What is the cost of the Echo on sale including tax? Round your answer to the nearest penny.

$96.74

Step-by-step explanation:

The original cost of the Amazon echo = $99.99

Then we have a 10% sale which we are going to subtract from the original cost.

= $99.99-(99.99x10%)

= 99.99-9.999

= $89.991

Then a tax of 7.5% was added

= $89.991 + (89.991 x 7.5%)

= 89.991 + 6.749325

= $96.740325

Therefore the cost of the echo including tax is $96.74
