If x varies directly with y and x = 2.5 when y = 10, funny x when y = 16.

Should be 4.0 (Not sure tho. my thought process is complicated but to me it makes sense)

Step-by-step explanation:

If y=10 and x = 2.5, if y were to = 20, then x would equal 5. so you take that ratio, and say 6 is 3/5's the way to 10, so you also divide 2.5 by 3/5

you get 1.5, you add that to x already and you get 4.0

so if y=16, x should = 4.0
