if y is a direct variation to x and y = 24 when x = 6 what is the value of y when x = 5

Question

the answers choices are

A.4

B.5

C.9

D.20

Answer 1

y is direct variation to x  then y = kx

Given numbers form a ratio expressed as y/x = 24/6

To find y when x = 5

We set up another ratio is y/5.

By the definition both ratios are equal 24/6 = y/5

4 = y/5

Multiple to each side by 5.

4*5 = 5y/5

y = 20
