Answer:
16
Step-by-step explanation:
there are 4 in a pack of 50.
200/50=4.
4x4=16.
Sue = 2 Sally
Sara = Sue - 1
= (2Sally) - 1
Sally + Sue + Sara = 49
Sally + 2 Sally + 2 Sally - 1 = 49
5 Sally = 49 + 1
5 Sally = 50
Sally = 10
Sue = 20
Sara = 19
The answer is A because if you subtract 100-23-58 you get 19 then you simplify it
The unit rate for $240 per 4 days is $60 per 1 day.
To get a unit rate you must simplify the rate down to $X per 1 day.
To get 4 days down to 1 day you must divide 4 by 4.
Doing the same to the other side you divide 240 by 4.
So now you have $60 per 1 day.
