300+60 +8 = 368 so 300+60+8 matches with the first box
3,000+600+80 = 3,680 so 3,000+600+80 matches with the second box
30,000+600+80= 30,680 so 30,000+600+80 matches with the third box
that's it!

Answer:
Yes, John did write his systems of equations correctly.
Step-by-step explanation:
FedEx charges him a flat rate of $5, so the 5 stands alone in the problem, and $0.50 per pound, so the 0.5 stands with the x because it represents each pound.
UPS doesn't charge him a flat rate so there is no stand-alone number. Since they charge $2 per pound, 2 is with the x, again representing each pound.
Method1:parabola
y = x^2 - 2x + 8
y-7 = (x-1)^2 ; parabola
turning point is (1,7)
method2:diff
y = x^2 - 2x + 8
y' = 2x -2 = 0 ==> x = 1,
y=7
$90 because you take the discounted price then divide it by .40 (40%)
