Question

why are equations and inequalities helpful to business?

Answer 1

equations let you model income and expense... and inequalities show the limits on income and expenses...

Answer 2

think about it this way

you have a mortgage to pay, plus utility bills and other expenses at home
you work full time and make $2,000 a month

your mortgage is $900
your other bills are $500

and you want to go to the shopping mall to buy some clothing and appliances
so to know your budget, you know you can't spend $2,000 at the mall

but you know you have some money to spend

so the amount to spend at the mall will be greater than 0, less than $2,000
if you add up your bills to $1,400
that leaves you $600 for the mall

so you can spend at the mall 0 < mall expenditure <= 1400

Answer 3

if you had a business, will be the same thing
you have a budget to manage and bills to pay all that from whatever income your business is getting

Answer 4

so you can spend at the mall 0 < mall expenditure <= 600
