Here, we want to get what should have been written as step 1

As we can see from what is presented, she went directly to step 2 without writing out the individual product and summing them

So, we have the step 1 correctly written as;

[tex]0.520\text{ = }\frac{(28)\text{ + (94) +(3) + 240}}{AB}[/tex]
