Answer:
3.8
Step-by-step explanation:
5% times 20 is 100% and that is the number we are trying to find so of we multiply .19 by 20 we should get 3.8 wich is promotional to the 100%
Rewrite the equation as;
-0.3(7n - 31.2) = 0.456
Divide each term by 0.3 and simplify;
-7n + 31.2 = 1.52
Move all terms not containing n to the right side of the equation;
-7n = -29.68
Divide each term by -7 and simplify;
<u>n = 4.24 </u>
