Using proportions, the expected number of adults in Palm City whose main source of news is the internet or newspaper is of 19,413.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
From the table, the proportion of adults in Palm City whose main source of news is the internet or newspaper is found as follows:
p = (62 + 88)/(62 + 88 + 128 +24 + 38) = 0.4412.
Hence, out of 44,000 adults, the expected number is found as follows:
0.4412 x 44000 = 19,413.

Step-by-step explanation:
<u>The marked price of the article was $7865</u>
Answer:
solution given:
let marked price be x=?
discount =20%
vat=13%
selling price =$7232
we have
<u>discount amount=discount % of marked price</u>=20/100*x=0.2 x
and
<u>vat amount = vat% of selling price</u>=13/100*$7232=$940.16
we have
<u>Selling price with tax =marked price - discount amount + vat amount</u>
$7232=x-0.2x+$940.16
$7232-$940.16=x-0.2x
0.8x=$6291.84
x=$6291.84/0.8
x=<u>$7864.8</u>
