Question

A pair of Sneakers cost $112 after it was marked up by 75%. How much

did it cost before the mark-up?

Answer

Divide the gross profit by the cost and multiply by 100 to calculate your percentage markup. In the example, divide $75 by $100 which equals $0.75, and multiply by 100 to give you 75 percent. Your markup on cost price is 75 percent.

Therefore, the answer would be (196)

Answer:

i believe the answer would be $448

a Carver begins work on the following block of granite that weighs 2700g what is the density of the granite ​

Answers

Density" of the given granite block is 2.7g/cm

.

Explanation:

Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=

v

m

where, “m" mass of an object and "v" is volume of an object.

Given that,

Dimensions of the block are 20 cm, 5 cm and 10 cm.

\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h

\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10

\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm

3

.

Mass of the block is 2700 g.

Substitute the given values in \rho=\frac{m}{v}ρ=

v

m

to find density of a block.

\rho=\frac{2700}{1000}ρ=

1000

2700

\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm

3

\text { "Density" of the given granite block is } 2.7 \mathrm{g} / \mathrm{cm}^{3} "Density" of the given granite block is 2.7g/cm

Would you rather, $20 off your entire purchase or 20% off your entire purchase?
(I need at least 2 good reasons why, please help!) < 3

Answers

Answer:

i personally would much rather have $20 off, because as the price goes up the less money you get off of the total price. but with $20 off, youre automatically getting $20 off. if you were to get %20 off of something that is $50, youd only get about $10 off, but if you used the $20 off coupon, you would get $20. which would be much better. so instead of partially getting some of it off, you can get a much larger amount off
