<u>Answer</u>
20%
<u>Explanation</u>
let the cost of tie = x
Then cost of a pair of pants = (100+50)%x
= 150%x
= 1.5x
The cost of shirt = (100+25)%x
= 125%x
= 1.25x
(1.5x - 1.25x)/1.25x × 100
0.25x/1.25x × 100
0.2 × 100 = 20%
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.

Answer: $542
Step-by-step explanation:
Given the following :
Selling price of refrigerator = $677.50
Markup = 25% of dealers' cost
Dealers' cost of refrigerator =?
Selling price = Dealers' cost + markup
Markup = 25% of dealers' cost
Let dealers' cost = d
Hence,
Selling price = d + 25% of d
Selling price = d + 0.25d
Selling price of refrigerator = $677.50
Then,
$677.50 = d + 0.25d
$677.50 = 1.25d
d = $677.50 / 1.25
d = $542
