mike and his friends are going to south padre for spring break. mike has excellent connections and can rent a house for $450 for the week. the plans were made and everyone contributed equally to the $450. yesterday, mike found out that 3 people caught the flu and couldn't go on the trip. he refunded their money. now mike has to collect an extra $5 from each person to cover the missing cost.
c)how many people were originally going on the trip? how many are now going
d) what are the domain & range for this situation?
