The price of a ring was increased by 9% to £1800. What was the price before the increase? Give your answer to the nearest penny.
tekilochka [14]

Answer:

1651

Step-by-step explanation:

let s say that the price before the increase is x

to apply an increase of 9% it does x + x*0.09 = x*(1+0.09)=x*1.09

and we know that this value is 1800

so

x*1.09=1800

<=>

x = 1800/1.09=1651.376147

to the nearest penny it gives 1651

A printing company is considering buying a new printing press. It has quotes from two different companies. Company A offers a pr
Ostrovityanka [42]
The complete problem wants to know the more cost-effective choice is the printing company replaces its press machine every four years. With this in mind, if they choose Company A, the total amount that needs to be paid to cover 12(4) = 48 months will be Company A = 9 500 + 48(750) = $13 100 As for Company B, the highest probability of not having any repairs over the four years is 0.32 while there's 0.14 chance that number of repairs will be 3 over the time the contract is applied. This means that the possible amounts to be paid to Company B are Company B = 10 500 + 0(150) = $10 500 Company B = 10 500 + 1(150) = $10 650 Company B = 10 500 + 2(150) = $10 800 Company B = 10 500 + 3(150) = $10 950 This shows that choosing the machine from Company B would be better. Hence, the answer is Company B<span>.</span>

From 1994 to 1995 the sales of a book decreased by 80%. If the sales in 1996 for the same as in 1994, By what percent did the in
zheka24 [161]

Answer:

400%

Step-by-step explanation:

Let the sales be "100" in 1994

Since, it decreased 80%, the sales was:

80% = 80/100 = 0.8

0.8 * 100 = 80 (decreased by 80)

So, it was

Sales in 1995: 100 - 80 = 20

Sales in 1996 was same as in 1994, so that's 100

Thus,

Sales in 1994: 100

Sales in 1995: 20

Sales in 1996: 100

We need to find percentage increase form 1995 to 1996, that is what percentage increase is from 20 to 100?

We will use the formula:

\frac{New-Old}{Old}*100

Where

New is 100

Old is 20

SO, we have:

\frac{New-Old}{Old}*100\\=\frac{100-20}{20}*100\\=4*100\\=400

So, it increased by 400%
