I the week starts on Monday he will fill Monday and Saturday and on each Monday he will wash his car
The answer is a the more balls means the more chance a desired color will be chosen
Y = mx + c
7= (-5)(-2)+ c
7= 10 +c
7-10=c
-3=c
Equation of the line: y = -5x-3
Sub in (a, 2)
2= - 5(a)-3
2+3= -5a
5= - 5a
1= - a
A = -1
C(t)= -0.3t^2 + 7.2t - 3.2
12c = 40
