Oranges
2(3.50) = 7.00
apples
4(3.25) = 13.00
carrots
2(1.90) = 3.80
potatoes
1(1.20) = 1.20
7 + 13 + 3.80 + 1.20 = 25.00 * .05 = 1.25
$25.00 - 1.25 = $23.75
The average rate of change over the interval is 2.17
Explanation:
Given that the cost of a floral bouquet after a discount is given by the function
We need to determine the average rate of change over the interval
The average rate of change can be determined using the formula,
where and
Substituting the value of a and b in the function, we get,
Hence, substituting these values in the formula, we get,
Simplifying, we get,
Dividing, we have,
Thus, the average rate of change over the interval is 2.17
A function is denoted as y = f (x), where x is the argument or input of the function. This means that from f(6) follows that x= 6, and to get the answer we should replace x with 6.
f(6)=6^2÷ 3 + 6= 36÷ 3 + 6= 12+6= 18
f(6)=18
