Lucy had to sew 182 windbreakers. She sewed 8 windbreakers each day from Monday to Friday and 14 each day on Saturday and Sunday. Starting on a Friday, on which day of the week did Lucy finish sewing all the windbreakers? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Lucy sewed on the first week = 1

Number of windbreakers that Lucy completed for from Friday to Sunday on the first week
= 1 x 8 + 2 x 14 
= 8 + 28
= 36

Number of windbreakers left to sew
= 182 - 36
= 146

Number of windbreakers that Lucy could sew per week from second week onwards
= 5 x 8 + 2 x 14
= 40 + 28
= 68

Number of weeks that Lucy needed to sew 146 windbreakers
= 146 ÷ 68
= 2 r 10

Number of days that Lucy needed to sew 10 windbreakers
= 10 ÷ 8
= 1 r 2

Lucy needed 1 more day to finish sewing the remaining 2 windbreakers.

Day of the week that Lucy completed her sewing
= 1 + 1
= 2 (Tue)
