From the statement, we know that we earned $1,520 in 8 weeks.
The ratio of money earned per week is given by the quotient between the amount of money earned and the time:
[tex]rate=\frac{\text{ammount of money}}{\text{time}}=\frac{\text{ \$1,520}}{8\text{ weeks}}=\frac{\text{ \$}190}{\text{week}}\text{.}[/tex]Answer
The rate of money earned is $190 per week.
