Let's say Jordan worked for x hours walking dogs.
The total amount of money he made dog walking is $10*x.
He also worked for x+3 hours as a lifeguard.
The total amount of money he made lifeguarding is $13*(x+3)=13x+39.
The sum of the amounts of money he made walking dogs and lifeguarding is $177, meaning $10*x+13x+39=$177.
The equation simplifies to 23x+39=$177.
Subtracting 39 from both sides gives 23x=$177-39=138.
Finally, dividing both sides by 23 gives x=138/23=6.
Jordan worked for 6 hours walking dogs.
He also worked for 6+3=<<6+3=9>>9 hours lifeguarding. Answer: \boxed{9}.
Jordan is working two summer jobs, making $13 per hour lifeguarding and $10 per hour walking dogs. Last week Jordan earned a total of $177 and worked 3 more hours lifeguarding than hours walking dogs. Determine the number of hours Jordan worked lifeguarding last week and the number of hours he worked walking dogs last week.
