Bill needs to earn $28 on Sunday so that the average is $22 each day, the correct option is C.
The graph is a mathematical representation of the relation between two objects.
Bill works as a waiter and he keeps track of the tips that he earns daily.
The tip earned on Monday is $14
The tip earned on Tuesday is $12.
The tip earned on Wednesday is $13.
The tip earned on Thursday is $25
The tip earned on Friday is $32
The tip earned on Saturday is $30
Average is the mean of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.
The average money that he wants to make by tip is $22
Let the tip earned on Sunday is $x.
Then by the formula of average
22 = ( 14+ 12 + 13+ 25+ 32 + 30 +x ) / 7
Multiplying 22 by 7
154 = 14 + 12 + 13 + 25+ 32 + 30 +x
154 = 126 + x
x = $28
