Alba was paid $135 for watching her neighbor's dogs for 9 days.

how much did alba earn per day?

!5.00 dollars and hour, since 15 times 9 is 135

To find the answer simply divide the total amount paid ($135) by the number of days (9).

135 ÷ 9 = 15

Alba earned 15 dollars per day.

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
