I need help with this question ASAP.

The answer is that Topsoil costs 10$ more than mulch.

When we look at the equation y=20x, we see that for one cubic yard, it costs 20$. when we look at the graph, we see that for one cubic yard it costs 30$ for topsoil, therefore, Topsoil is $10 more than mulch for each cubic yard.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

i’ll just s take the points thxs
