Ursula bought 5 hot dogs at $1.50 each, so she spent 5 x $1.50 = $7.50 on hot dogs.
She also bought 3 salads at $2.50 each, so she spent 3 x $2.50 = $7.50 on salads.
In total, she spent $7.50 + $7.50 = $15 on hot dogs and salads.
Ursula paid with two $10 bills, so she paid a total of $10 + $10 = $20.
To find her change, we subtract the total amount she paid from the total amount she spent: $20 - $15 = $5.
Ursula got $5 change back.
#### 5
The answer is: 5
