The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W

Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2 46.5

5 116. 25

7 162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

$2 \; \rm Jackets =\$ 46.50$

$1 \;\rm Jacket = \dfrac {\$46.50}{2}$

$1 \;\rm Jacket = \$ 23.25$

Now the cost price of 3 jackets is given as,

$3\;\rm Jackets = \$23.25 \times 3$

$3\;\rm Jackets = \$69.75$

Hence we can conclude that the cost price of 3 jackets is $69.75.

A TV has a listed price of $647.99 before tax. If the sales tax rate is 9.75%, find the total costs of the TV with the sales tax

Lena [83]

Answer:

$647.99

Step-by-step explanation:

Divide the tax rate (9.750%) by 100 to get a decimal rate of 0.09750.

Add 1 to the decimal rate to get 1.09750.

Divide that tax-included price ($647.99) by 1.09750 price to get a pretax price of $590.42.

Subtract the pretax price from $647.99 to get the sales tax amount of $57.57.
