I'm stuck on these questions for my homework anyone knows if they are linear or nonlinear. and I need to know how to write them as a function.

Question

A. Jordan sells watches from an online business. On average, he sells 75 watches a week, for $50 each. This week, he sold only sold 30, so he held a 40% off sale to stimulate more sales. He sold the watches for $30 each during the sale.

B. An online clothing business, on average, gets 600 sales for $25 jackets every 2 months. Recently, they only made 389 sales because their business rival was holding a fall/holiday sale for the season and had varying prices.

Answer 1

whenever you see phrases like

"each" and "for every"

involving constant amounts, then that indicates a linear function.


For example, in A:
If x is the number of watches sold, and y is the revenue, then
y = 50x
the new discount price is 40% off, or 60% of the normal price so
y = (50 * 0.6)x = 30x

Answer 2

Thanks, I understand a bit better now
