Input usually means x and output is y
So triple mean 3
You have 3x than
Output is means y=
Y=3x is what we have now
So five less is -5
Y=3x-5 should be the final answer
Hope this helps!
Answer: 15 packs per hour
======================================================
Work Shown:
y = change in number of packs sold
y = 57 - 12
y = 45 packs
x = change in time (in hours)
x = 3 hours
m = slope = rate of change
m = y/x
m = 45/3
m = 15
The store sold 15 packs per hour during the timespan of noon to 3:00 pm.
The easiest way to solve it is to multiply all the choices together.
3 pants x 4 vests x 2 shoes = 24 different ways
if your unsure of your answer, you can always draw a tree diagram.
0.712, 0.700+0.010+0.002=0.712
price after discount = t - 1/3 t
= 2/3 t
so option B and E are correct answer
