Toby exercises 14 hours a week. john exercises 20% more than toby and jenny exercises two more hours than john. which expression represents how much jenny exercises in w weeks? a) 13.2w b) 16.8w c) 18.8w d) 19.2w

C. 18.8w

Step-by-step explanation:

Since Toby exercise 14hours a week, and John exercises 20% more than Toby

John increment in number of hours compared to Tobi will be;

20/100 ×14 = 2.8hrs

This shows John exercises 2.8hrs more than Tobi. Total number of hours exercised by John will become;

14+2.8 = 16.8hrs

Since Jenny exercises two more hours than John, Total number of hours exercised by Jenny will be;

16.8hrs+2hrs

= 18.8hrs/week

If Jenny exercise 18.8hrs in a week, it means she will exercise 18.8×w/1 in w weeks which gives 18.8w weeks.

Step-by-step explanation:

The number of hours that Tobi exercises in a week is 14 hours.

John exercises 20% more than Toby. The number of hours by which John exercises more than Tobi is

20/100 × 14 = 2.8hours

The number of hours that John exercises in a week is 14 + 2.8 = 16.8 hours.

Jenny exercises two more hours than John. The number of hours that John exercises in a week would be

16.8 + 2 = 18.8hours.

The expression representing how much Jenny exercises in w weeks would be

w × 18.8 = 18.8w hours
