Answer:
47.33
Explanation:
Hey there! I'm happy to help! 
 
We have 8 bags of dog food and each costs $25.19 
 
8(25.19)=201.52 
 
And we have 11 leashes each costing $4.65. 
 
11(4.65)=51.15 
 
We add these totals up. 
 
201.52+51.15=252.67 
 
We subtract this from 300 to see how much is left. 
 
300-252.67=47.33 
 
Rhonda had $47.33 left after her purchases. 
 
Have a wonderful day! :D
