⌊x⌋ floors the input x. It will always round x down to the an integer that is lower.
Then that is multiplied by 4.
This results in
                                      g(5.7) = 4⌊5.7⌋
                                      g(5.7) = 4 * 5
                                      g(5.7) = 20
The answer to this question is 20.

Fittoniya [83]

Answer:

day 540

Step-by-step explanation:

He increases his number of situps by 2 each day meaning on day 1 he'd do 2 extra, on day 2 he'd do 4 extra, on day he'd do 6 extra etc. We can show this by saying +2x where x is the day he is on. Then since he started with 20 we have to add 20 so it would be 20+2x. We want to know what day it is when he does 1100 situps so we can set our equation equal to 1100 and solve for X which is the day it would be.

20+2x=1100

2x=1080

I hope this helps and please don't hesitate to ask if there is anything still unclear!

x=540
