Answer:1

Step-by-step explanation: substitute all the corresponding terms so you get, 16=4(3+b2)

Then you multiply and get 16=12+4b2 then subtract 12 from both sides to get 4=4b2 and then divided both sides by 4 and you get 1=b2

Dora bought a bottle of nail polish that was marked down by 20 percent from its original price of $4.50. Including a 9 percent s
igomit [66]

Answer:

3.92$

Step-by-step explanation:

The first step is to deduct 20% of 4.50 from 4.50.

20% of 4.50 is 0.2 x 4.50 = .90

4.50 - 0.90 = 3.60

That's the new price without the sales tax.

Now we need to add 9% of 3.60 to 3.60 to get the final cost.

9% of 3.60 is .09 x 3.60 = 0.32

3.60 + .32 = $3.92

Alice Smith bought a clothes dryer that retailed for $325 . She received a 15% discount because she works at the store where she
r-ruslan [8.4K]

Answer:

296.97

Step-by-step explanation:

Remark

The first thing you have to realize is that you take the discount before you add the sales tax.

Discount

If she receives a 15% discount, she still pays 85% of the full price.

85/100 * 325 = 276.25

Sales Tax

A sales tax is only added on after a goods or service has been determined and agreed upon by the buyer and seller.

The sales tax can be calculated quickly by adding the decimal equivalent onto 1 and multiplying that by the discounted amount.

1 + 7.5% = 1 + 7.5/100 = 1 + 0.075 = 1.075     deriving the discount amount

Cost

Cost = discounted price * 1.075                    Substitute in Formula

Cost = 276.25 * 1.075                                    Simplify

Cost = 296.97                                                Answer
