Assume Charles charges $7*3=$21 if he babysits for 2,5 hours (that is 2 and a half hours).
That is we are not considering Charles babysitting exactly 1, 2, 3 or 4 hours, but also in between times.
then we can write the following piecewise function to describe the situation:
f is a function from (0, 4] to {$7, $14, $21, $28}
I’m not sure but I think the answer would be 40
Answer:
Yes
Step-by-step explanation:
since it is -21/21 you can divide it by 21, -21/21=-1, 21/21=1
hence, -1/1
-1/1=-1
