Step-by-step explanation:

if interest (I) varies directly as interest rate (R)

Then

I ∝ R

I=cR

c= constant

if interest is $47 when interest rate is 5%

47 =.05c

if interest rate is 5.2% then

I = 940 x .052

=48.88

hichkok12 [17]

Answer:

There are approximately 88 adults.

Step-by-step explanation:

The question is:

A fair was attended by 350 people of which two thirds are adolescents and a quarter adults and a fifth are children from 10 to 12 what amount corresponds to adults .

Solution:

Total number of people attending the fair is, <em>N</em> = 350.

The proportion of adults is: P (Adults) = <em>p</em> = 0.25.

Compute the number of adults in the fair as follows:

$\text{Number of adults in the fair}=N\times p$

$=350\times 0.25\\\\=87.5\\\\\approx 88$

Thus, there are approximately 88 adults.
