The price of a four-star dinner was $100 two decades ago. A report says that a dinner is 250% of what it was 20 years ago, how m
Nina [5.8K]

The dinner will cost $250 today.

<u><em>Explanation</em></u>

The price of a four-star dinner was $100 two decades ago and now the cost of the dinner is 250% of what it was 20 years ago.

So for finding the current cost, we will find 250% of $100 .

First we need to make 250% as decimal form after dividing it by 100. So....

250% = \frac{250}{100}= 2.50

Now we will multiply this 2.50 with $100 for getting the current cost of the dinner.

Thus, the current cost =(100* 2.50)dollar = 250 dollar

Factor the expression below
Mazyrski [523]

Answer:

(2x² + 5x + 2) = (2x + 1)(x +2)

Step-by-step explanation:

Given expression is (2x² + 5x + 2).

We have to factorize the given expression.

(2x²+ 5x + 2) = 2x² + 4x + x + 2

                     = 2x(x + 2) + 1(x + 2)

                     = (2x + 1)(x + 2)

So the factored form of the given expression will be (2x + 1)(x + 2).

Bridget and Caroline win some money and share it in the ratio 7:3. Bridget gets £40 more than Caroline. How much did they get al
solong [7]

Answer:

£100

Step-by-step explanation:

if the ratio is 7:3, the difference between them is 7-3 . = 4.

So,

4x = £40

Now, calculate x

x = £10

Now,

we are able to calculate:

7x (Bridget's share) = £70

3x (Caroline's share) = £30

Sum = £100

Hope this helps.

Good Luck
