A plane has 360 total seats which are divided into economy class and business class for every 13 seats in economy class there are five seats in business class how many seats are there in each class

There are 260 seats in economy class and 100 seats in business class

Step-by-step explanation:

To solve this problem we first have to calculate the fraction of economic and business seats with respect to the total

We are told that every 13 seats in economy class there are 5 seats in business class

13 + 5 = 18

This means that if there are 18 seats 13 will be economic and 5 business

economic seats = 13/18

business seats = 5/18

To find out the number of seats in the airplane of each class, we have to multiply the total number of seats by these fractions

economic seats = 360 * 13/18

economic seats = 260

business seats = 360 * 5/18

business seats = 100

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
