Answer:
40 minutes.
Step-by-step explanation:
- time spent on the thread mill as a function of d(day) = t(d)
= 30 +2(d-1) minutes
[where d represents day number]
(when d is 1 the time spent should be 30
so substitute d=1 and check it will be 30 only.
on first day he will spend 30 minutes so, I added 30 .
and on every additional day( these additional days are excluding first day), he will increase the time by 2 minutes.so, I added 2(d-1) to initial 30 minutes)
- so, T(6), the minutes he will spend on the treadmill on day 6=
=30+2(6-1)
=30+2(5)
=30+10
=40 minutes
I can help you but what is the operation of math

d = # of days
Step-by-step explanation:
15 food
23 game
Total Money = M = 15 * 75 + 9 d + 23* 65 + 7d
M = 15 * 75 + 9 d + 23* 65 + 7d
M = 1125 + 1495 + 16d
M = 2620 + 16d
