Answer:
Justine washed 8 dogs on Sunday .
Step-by-step explanation:
price charged by Justine to wash one dog =$25
Number of dogs washed on Saturday =5
Money earned on Saturday = 5*25 =$125
Total money earned on the weekend = $325
Money earned on Sunday = $325-$125=$200
Number of dogs washed on Sunday = 200/25 =8
Hence , Justine washed 8 (eight ) dogs on Sunday .
