Xandra had to sew 213 jackets. She sewed 8 jackets each day from Monday to Friday and 12 each day on Saturday and Sunday. Starting on a Monday, on which day of the week did Xandra finish sewing all the jackets? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Xandra sewed on the first week = 5

Number of jackets that Xandra completed for from Monday to Sunday on the first week
= 5 x 8 + 2 x 12 
= 40 + 24
= 64

Number of jackets left to sew
= 213 - 64
= 149

Number of jackets that Xandra could sew per week from second week onwards
= 5 x 8 + 2 x 12
= 40 + 24
= 64

Number of weeks that Xandra needed to sew 149 jackets
= 149 ÷ 64
= 2 r 21

Number of days that Xandra needed to sew 21 jackets
= 21 ÷ 8
= 2 r 5

Xandra needed 1 more day to finish sewing the remaining 5 jackets.

Day of the week that Xandra completed her sewing
= 2 + 1
= 3 (Wed)

Answer(s): 3
