The cost of a floral bouquet after a discount is applied is represented by the function below, where x represents the number of
flowers in the bouquet.
F(x) = $2.17x - $10.00
What is the average rate of change over the interval (12.24]?

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

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
