Answer: The mechanic worked for 4.25 hours for the fourth customer.
First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60
Slope: 60
Then find out what the y-intercept is by plugging in values we know into y=mx+b
90=60(1)+b
30=b
Y=60x+30
Substitute the y with 285 to find out the x (hours)
285=60x+30
4.25=x
You would make it into an equation then solve it after creating that equation. When you hear the word "each" that should give you a clue or a sense that should be a variable. So in this case it would be:
17x+21=157
Then you would solve it from there. Once you find x you'll know how many workbooks Norwood Middle School purchased.
