Jason works as an administrative assistant for a local lawyer's office. the office is running low on pens and notepads, so he is asked to buy $150 worth of pens and notepads. pens cost $1, and notepads cost $2. if the number of pens he buys is represented by x and the number of notepads he buys is represented by y, the situation can be given by x + 2y = 150, where 0 ≤ x ≤ 150, 0 ≤ y ≤ 75 and x and y can take only integer values.

Case 1: Assuming that the stationery store is out of notepads, then y=0

x + 2y = 150

 x = 150

Case 2: Assuming that the stationery store is out of pens, then x=0

x + 2y = 150

2y = 150

y = 75

the answers c

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
