Nastasia [14]

Given:

Spoilage rate of fruits = 9% = 0.09

To find:

Amount of fruits to be order to have 100 pounds of peaches and considering the spoilage rate.

Solution:

Let the required amount of fruits you should order be x.

So, spoiled fruits = 9% of x = 0.09x

He would like to have 100 pounds of peaches to sell.

x-0.09x=100

0.91x=100

Divide both sides by 0.91.

x=\dfrac{100}{0.91}

x=109.89

x\approx 110

The required amount of fruits to be order is 110 lbs. Therefore, the correct option is D.

The gestation period of rhinos ​(487 ​days) is​ _____ percent longer than the gestation period of bears ​(220 ​days).
Talja [164]

Answer:

The gestation period of rhinos ​(487 ​days) is​ 121. 3 percent longer than the gestation period of bears ​(220 ​days).

Step-by-step explanation:

Given:

Gestation period of rhinos = 487  ​days

Gestation period  of bears = 220 ​days

To Find:

Percentage increase = ?

Solution:

The percentage increase =\frac{ \text{new value} - \text{final value} }{\text{final value}} \times 100

On substituting the  values,

= \frac{ 487 - 220}{220}\times 100

=\frac{267}{220}\times 100

=>1.213 \times 100

=> 121.3 %
