I need help with these 2 questions my dudes. I have tried solving them, but I don't know what I'm doing.

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
