The first group was responsible for making 160 suits while the second group was responsible for making 25% fewer suits in the same amount of time. The first team made 10 more suits each day than the second team and finished its job 2 days before the deadline date. How many suits did the second team make each day if it needed two days extra after the deadline to finish the assigned job?

Answer 1

group 1: 160 suits
group 2: 3/4 * 160 = 120 suits

If the 2nd team made x suits per day, then since it took 4 more days,

160/(x+10) + 4 = 120/x
x = 10

extra credit: how many days did the teams work?
