Answer:
I am assuming the question how many miles did they run last week so.
Step-by-step explanation:
d=6(because sunday was 5 miles we don't count that)
3.5*6=21
21+5=26
Erin ran 26 miles last week.
d=6(because sunday was 3 miles we don't count that)
2.5*3=7.5
7.5+3=10.5
Luis ran 10.5 miles
In case the question was how many more miles did Erin run than Luis it would be, Erin ran 15.5 more miles than Luis.
Hope this helps.
