Question 1000364: Find the missing value for each variation
If Y directly proportional to X and Y = 5 when X = 1, find Y when X = 20

Hi there,
Y directly proportional to X
Y = kX
k is the constant of proportionality
Find 'k'
Y = kX
5 = k1
k = 5
Formula:
Y = 5X
.......
Y = 5 x 20
Y = 100
Hope this helps. :-)
