3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?

Answers

Answer:

$74,750

Step-by-step explanation:

Given that,

The cost of a computer = $65,000 + value added tax at 15%

We need to find the amount the computer actually cost the customer.

Total cost = Cost of computer + VAT at 15%

[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]

So, the computer actually cost the customer is $74,750.

Your friend wants to buy a pair of jeans
that are on sale for 30 off if the jeans
original price is $40, how much will the
sale price be?

Answers

Answer:

$12

Step-by-step explanation:

30 x 40

100

= 12

The sale price is $12.

The price of the pair of jeans that are on sale for 30% off will be $28.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Your friend wants to buy a pair of jeans that are on sale for 30% off if the jean's original price is $40.

Let "S" be the price of sales. Then the equation is given as,

30% = [($40 - S) / $40] x 100

0.30 = ($40 - S) / $40

S = $40 - $12

S = $28

The price of the pair of jeans that are on sale for 30% off will be $28.

She sells each glass of lemonade for £1.50.
If she sells 30 glasses of lemonade, what is her total profit?

Answers

Answer:

her total profit is 3

Step-by-step explanation:

1.50 x 30 = 45

to find total profit - 45-42= 3

Her total profit would be £3.
£1.50 multiplied by 30 glasses equals £45
You then subtract £45-£42 to get £3 profit.

Answer: x = 4

Step-by-step explanation:

since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.

so, i redrew them next to each other, so i could compare them easily.

i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!

so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.
