Suppose y varies inversely with x and that y=2 when x=8 what is an equation for this inverse variation?
a. y=8/2x
b. y= 2/8x
c. y= x/16
d. y= 16/x
is the answer a?

answer is 

D. y= 16/x

cause

y = k/x

2 = k/8

2(8) = k

k = 16

y=16/x

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
