I can't understand this question for some reason! can anyone help me to figure it out?
question:
The owner of 40 apartments knows that, at a rent of $360 per week, all apartments will be occupied. For each increase in rent of $30 per week, one fewer apartment will be occupied. He increases the rent from $360 per week to $(360 + 30x ) per week. After this increase, the total income he receives is $R per week
Show that R = 14 400 + 840x - 30x^2
any help would be really appreciated!
