Answer:
$630
Explanation:
The total amount of money Steve earns in a 35 hour week will be sum of the amount he earns from tips and the amount he earns from wage.
In a 35-hour week, Steve earns 35*8=$280 from tips at $8/hr and 35*10=$350 from his work wage of $10/hr.
Therefore he makes a total of 280+350=$630 in a 35-hour week.
