Am selling widgets. They cost $2 to make. If I price the widgets at $20 each, I can only sell one. If I price them at $1 each, I can sell 20. Assume that demand is a straight line between those points. 1. How many do I sell at $5 each?
2. What is the total cost to make them (cost each times # sold)?
3. What is the total revenue I make from selling them (price I sell each times the
number sold)?
4. What is my profit (revenue-cost)?

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
