Step-by-step explanation:

Uh I don’t think so.
Sorry! But stay safe! :)
When it says x and y are directly related it means that x is multiplied by something to get y. To solve you divide y by x which is 840 divided by 6. Which is 140 then you multiply and solve so the y value for 5 is 700. The x value for 420 is 3 and the y value for 4 is 560.
First you subtract the 30 from 300 and than 270/45 and your answer will be A. 6
