The average price of a brand of coffee that you buy is $4.89 for each 11-ounce can. Depending on where you shop, the prices of this can of coffee vary by as much as $1.58. Find the minimum and maximum prices of this coffee.

Minimum price of the coffee = $ 4.1

Maximum price of the coffee = $ 5.68

Step-by-step explanation:

Let us assume

The minimum price of the coffee = $x

As given , the prices of this can of coffee vary by as much as $1.58.

⇒ Maximum price of the coffee will be = $ x+1.58

Now, as given , The average price of coffee = $4.89

⇒ = $4.89

⇒ Maximum + Minimum = 9.78

⇒x + 1.58 + x = 9.78

⇒2x + 1.58 = 9.78

⇒2x = 9.78 - 1.58

⇒2x = 8.2

⇒x = = 4.1

∴ we get

Minimum price of the coffee = x = $ 4.1

Maximum price of the coffee = x + 1.58 = $ 4.1 + 1.58 = $ 5.68

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,

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
