Answer:

y = 55

Step-by-step explanation:

Hi,    

Remember: if y and x are directly proportional, you could write a ratio with those values, as follows:

y:x becomes 22:6

You can write an equation with the new value:  

y:15 = 22:6

Now solve by cross multiplication. Imagine that those ratios are fractions:

y/15 = 22/6

y*6=15*22

6y=330

y=55

The value of y is 55 when x is 15.
