Question

The amount of money Jerome saves after w weeks is represented by the function f(w)=15w+230

Answer 1

Answer: The value of 15 represents that Jerome adds $15 every week to his savings.

Step-by-step explanation:

Given function: $f(w)=15w+230$ which represents the amount of money Jerome saves after w weeks.

Here 15 is the rate of increment in the saving per week as it is the slope of the function.

Put w=0, when Jerome started saving

$f(0)=15(0)+230=0+230=230$

Thus, 230 is the initial amount of saving.

Put w=1, for first week

The amount of money he saved=$f(1)=15(1)+230=15+230=245$

Increase in saving=245-230=15

Put w=2, for second week

The amount of money he saved=$f(2)=15(2)+230=30+230=260$

Increase in saving=260-245=15

⇒ Jerome is added 15 rupees per week.

Answer 2

15 represents the slope of the function. In other words it means that for every week Jerome earns 15 dollars more. Hope this helps :)
