What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The cost of electric toothbrush = $56

And, The price of markup = 40%

So, The cost for the store to purchase the electric toothbrush is;

=  (40% of $56)

= (40/100 x 56)

=  $22.4

The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an air
tensa zangetsu [6.8K]

The total time taken for round trip will be: (f+g)(x) = 14x+11

Step-by-step explanation:

Given

f(x) = 4x+13\\g(x) = 10x-2

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

(f+g)(x) = f(x)+g(x)\\= (4x+13)+(10x-2)\\=4x+13+10x-2\\=4x+10x+13-2\\=14x+11

Hence,

The total time taken for round trip will be: (f+g)(x) = 14x+11
