Answer:
0.1$ per apple
9.5$ per 35 apples
65 apples picked by Matteo
Step-by-step explanation:
Part D
That point on the graph (100, 16) is a hint, it means that for x= 100 apples the pay is P= 16
the equation is: P=bx+6
now we can substitute the values of the hint like this:
16=100b+6
10=100b
b=1/10=0.1 $ per apple
if one picked 35 apples she would get P=0.1*35 + 6 = 9.5$
Part E
you can write as equations
M=apples picked by Matteo
B=picked by Brooke=2M (twice as much as Matteo)
A=picked by Addie = M-20 (20 fewer than Matteo)
K=picked by Khan=M+50 (50 more than Matteo)
you know that M+B+A+K=355
and you can expresso those values in terms of Matteo like this
M+(2M)+(M-20)+(M+50)=355 those parenthesis are there only to show you each single substitution clearly
M+2M+M-20+M+50=355
5M=325
M=325/5 = 65
