We're looking for C(h), where h is the hundreds of shirts. The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500. Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect. I'll leave it to you to evaluate C(5).
Answer 8,050
Reason the absolute value of 8000 is 8000. The absolute value of negative 50 is 50. 8000+ 50= 8,050
Kx=y-m
x=(y-m)/k
Note that this is also standard linear form, x=y/k-m/k where slope=1/k and x intercept is -m/k.
Step-by-step explanation:
Distance = Speed x Time
Given Distance = 40km/h or kph
Time = 5 hours 15 minutes
=
Distance Travelled = 40 kph x 5.25 hours
= 210km
