Problema Solution
Sue and Roger collected 57 seashells while walking on the beach. Sue collected 2 more than 4 times the number Roger collected. How many seashells did each collect?
Answer provided by our tutors
Let S, R be the number of seashells collected by Sue and Roger
S+R=57.
S=4R+2.
4R+2+R=57.
5R=55.
R=55/5
=11.
S=57-11.
=46.
