The camera shop sells two popular models of digital slr cameras (camera a price: 200, camera b price: 300). the sales of these products are not independent of each other, but rather if the price of one increase, the sales of the other will increase. in economics, these two camera models are called substitutable products. the store wishes to establish a pricing policy to maximize revenue from these products. a study of price and sales data shows the following relationships between the quantity sold (n) and prices (p) of each model: na = 195 - 0.6pa + 0.25pb nb = 301 + 0.08pa - 0.5pb construct a model for the total revenue and implement it on a spreadsheet. develop a two-way data table to estimate the optimal prices for each product in order to maximize the total revenue. vary each price from $250 to $500 in increments of $10.

step-by-step explanation:

139 divided by a number

step-by-step explanation:

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

your answer would be b
