Hi Giselle,
Since the brother's hourly wage is 160% of his friend's wage, that would mean that the brother earns more than his friend. The percentage 160% is equal to 1.60 , which means that the friend's wage multiplied by 1.6 is the brother's wage.
We can write the following equation and solve it to determine the friend's wage
(represented by the variable, f):
1.60 • f = $10
Divide both sides of the equation by 1.60 to find f:
1.60 • f = $10
1.60 1.60
f = $6.25
