Question

worried about going over his storage limit, fred monitored the number of undeleted voicemail messages stored on his phone each day. according to the table, what was the rate of change between wednesday and saturday? round your answer to the nearest tenth. voicemail messages per day

Explanation:

Step1: Calculate the change in voicemail messages

The formula for the rate of change is $\frac{\text{Change in voicemail messages}}{\text{Change in days}}$.
The number of voicemail messages on Wednesday is $2$ and on Saturday is $10$.
The change in voicemail messages is $10 - 2=8$.

Step2: Calculate the change in days

From Wednesday to Saturday, the change in days is $6 - 3 = 3$ (assuming Wednesday is day 3 and Saturday is day 6 in a weekly count starting from Monday as day 1).

Step3: Calculate the rate of change

The rate of change $r=\frac{8}{3}\approx2.7$

Answer:

$2.7$
