If a large factory sells its new gadgets for $5 each it can sell 1050 per month if it sells the same gadgets for $9 it will sell 900 per month assuming the relationship between prices and sales is linear predict the monthly sales of gadgets to the nearest whole number if the price is $12

788 Since we're assuming a linear relationship between sales and price, let's create an equation for the two points that we know. The general form of the equation will be in slope intercept form, so s = ap + b where s = number of sales a = slope of line p = price b = y intercept. So let's calculate a first. a = (1050 - 900)/(5-9) a = 150/(-4) a = -150/4 a = -37.5 So we now have the equation s = -37.5p + b Let's substitute one of out known price, sales pairs and solve for b. s = -37.5p + b 1050 = -187.5 + b 1237.5 = b So now we have the equation: s = -37.5p + 1237.5 Finally, just plug in the value 12 for p and calculate s. s = -37.5p + 1237.5 s = -37.5*12 + 1237.5 s = -450 + 1237.5 s = 787.5 And after rounding to the nearest whole number, we get 788.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
