Problem
Nathan saves 5% of his weekly salary. If Nathan earns $380 per week, how much does he save per week?
Solution
For this case we can do the following proportional rule:
[tex]\frac{380}{100}=\frac{x}{5}[/tex]Where x represent the amount of money that Nathan saves per week and we can solve for x and we got:
x = 5 (380/100)= 19
And the best solution would be:
A. $19
