A manufacturing company finds that they can sell 625 items at $ 1.50 per item and 400 items at $ 3.00 per item. If the relationship between the number of items sold x and the price per item p is a linear one: Find a formula that gives x in terms of p : x =

Now use the formula to find the number of items they will sell if the price per item is$ 2.00. They will sell ___ items if the price is $ 2.00.

Let I = items

P = Price

then, the slope for a linear relationship is m = (400-300)/(2-2.5) = -200

I-400 = -200(P-2) or I = -200P + 800

at $1.50 per item, you can sell I = -200(1.5) + 800 = 500 items

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
