This is a practice lesson Jake makes and sells pies. He sells each pie for $5.75. The materials to make each pie costs Jake $4.00. The boxes Jakes put the pies in cost $0.75 each. Jake wants to know how many pies (p) he needs to sell to earn a profit of at least $50. Which inequality should Jake use? A) 50 ≤ 5.75p - 4.75p B) 50 ≥ 5.75p - 4.75p C)50 ≤ 5.75p - 3.25 D)P ≤ 5.75(50) - 4.75p

Option A is correct.

Step-by-step explanation:

Let p be the number of pies Jake sells. The profit Jake makes is the total price the pies are sold for ($5.75) minus the total cost of making them ($4.00 + $0.75 = $4.75). For the profit to be at least $50:

($5.75 - $4.75)p ≥ 50

Option A is another way of writing this answer (expand and flip).

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
