C and B is proportional relationships , because the proportional relationships always start at zero and the line must be straight !
There are many equations that has a constant of
proportionality, might want to make it more specific.
When trying to find a percent, it is best to multiply everything by 100 (as a percentage is out of 100). 0.03*100= 3 and 1*100=100. Therefore, 0.03 as a percent is 3%
Hope this helps :)
