20.90 would be the item before tax. To get the amount of tax, I multiplied 20 by 0.05 and subtracted that amount from 22
Hey there!
Since we don't have values for b, d, and r, we can't get a specific number for the value of a, if that makes sense. It'll be represented by these variables.
To solve, we need to make sure the equation looks like a = ? .
Subtract b from each side of the equation.
<u>a = dr - b </u>
Now we have solved for a.
Hope this helps!
Thw answer is -51
Found through long division
The answer is about 60ish. Hope this helped. :-)
