We Do! Carter got $60 in cash for his birthday. He decides to spend it on apps for his iPad. Each
app costs $2. Write an equation that represents the money he has left after buying *
amount of apps.
Question: Write a linear equation for the following information.
Step 1: Find the slope: Look for words like "per," or "each."
**If the question asks for total cost, it's positive. If it's asking for how much is left, then it's negative.
Step 2: Find the y-intercept: Remember that the y-intercept are initial values, what you started off with.
Step 3: Put it together in the form of y= mx + b

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
