What example from my line of work ( catering ) or daily life can be expressed as an inequality with one variable?
How do I set up the inequality and solve it.
:
I would imagine that you have fixed cost and cost per meal
:
Let's say your fixed cost = $500
Let the cost for making each meal = $3
Let the sale price of each meal = $5
:
To make a profit the sales have to exceed cost
:
How many meals do you have to sell to make a profit?
:
Let x = no. of meals made and sold
:
Sale$ greater than cost$
5x > 3x + 500
solve
5x - 3x > 500
2x > 50
x >
x > 250
;
You have to sell more than 250 meals to make a profit
