A stock decreased in price by $25 over 4 days. What was the mean daily decrease in price?

Answers

A mathematical mean is the average of a group of numbers.

The mean daily decrease would be the total amount of decrease (in this case, $25) divided by the total amount of days it took to get there (in this case, 4).

25 / 4 = 6.25 = 6 $(1)/(4)$

The mean daily decrease in price would be 6 $(1)/(4)$ .

The price of a gallon of milk went from $2.70 to $3.50 in four years. Find the rate of change of the price of milk.A) $0.10 per year
B) $0.20 per year
C) $0.50 per year
D) $0.80 per year

Answers

Answer: B)$0.20 per year

Step-by-step explanation:

Given: The previous price of a gallon of milk = $2.70

The new price of a gallon of milk = $3.50

Time to increase price = 4 years

Now, the rate of change of price of milk is given by:-

$k=\frac{\text{New price-Previous price}}{Time}\n\n\Rightarrow\ k=(3.50-2.70)/(4)\n\n\Rightarrow\ k=(0.80)/(4)\n\n\Rightarrow\ k=20$

Hence, the rate of change of the price of milk= $0.20 per year
