The Marked price of a jacket at a dealer's shop is 2400. The dealer allows a discount of 15% to the retailer. As the company's p

Andrej [43]

Answer:

2400

2640

360

Step-by-step explanation:

the retailer has to sell it for the same price as the dealer.

so, both mark it for 2400 sale price.

if a customer buys it at the retailer, the retailer makes the 15% discount he got from the dealer as profit.

2400 = 100%

1% = 2400/100 = 24

15% = 24×15 = 360

the retailer makes this profit no matter what other fees or taxes are added.

the final price is then including 10% VAT

2400 = 100%

10% = 24×10 = 240

final price = SP + VAT = 2400 + 240 = 2640

Determine the value of x to the nearest thousandth in the equation 8(2)^x+3=48

solong [7]

You probably mean either

$8\cdot2^x + 3 = 48$

$8\cdot2^{x+3} = 48$

Write 8 = 2³, so that in the first interpretation,

$8\cdot2^x = 2^3 \cdot 2^x = 2^{x + 3}$

and in the second,

$8\cdot2^{x+3} = 2^3 \cdot 2^{x+3} = 2^{x + 6}$

Then in the first interpretation, we have

$2^{x + 3} + 3 = 48 \implies 2^{x + 3} = 45 \implies x + 3 = \log_2(45) \implies x = \log_2(45) - 3 \approx \boxed{2.492}$

Otherwise, the second interpretation gives

$2^{x + 6} = 48 \implies x + 6 = \log_2(48) \implies x = \log_2(48) - 6 \approx -0.415$

What is the value of z?

babymother [125]

Answer:

Step-by-step explanation:

Item 1:

Discount = Original price - discount price

= 22.50 - 13.50

= $ 9

Discount percentage = $\frac{9}{22.50}*100\\\\$

= 40%

Discount percentage = 40%

Tax = 14.31 - 13.50 = $0.81

Tax% = $\frac{0.81}{13.50}*100\\\\$ = 6%

Tax percentage = 6%

Item 2:

Tax = 6% of 16.20

= 0.06 * 16.20

= 0.972

Tax = $ 0.97

Total price (including tax )= 16.20 + 0.97 = $ 17.17

x = $ 17.17

Item 3:

Discount = 40% of 32.50

= 0.4 * 32.50

= $ 13

y = 32.50 -13

y = $ 19. 50

Tax = 6% of 19.50

= 0.06 * 19.50

= 1.17

z = 1.17 + 19.50

Z =$ 20.67
