A large factory knows that if it sells it's new gadgets for $10 each, it can sell 350 per month and if it sells the same gadgets for $8 it will sell 500 per month assuming the relationship between price and sales is linear predict the monthly sales of gadgets to the nearest whole number if the price is $6.
Im really confused

if the relationship is linear, the line contains the points
(10,350) and (8,500)
so, the equation of the line is
y350 = 75(x10)
so, when x=6,
y = 75(610)+350 = 650
