Hazel had to sew 131 jackets. She sewed 7 jackets each day from Monday to Friday and 14 each day on Saturday and Sunday. Starting on a Tuesday, on which day of the week did Hazel finish sewing all the jackets? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Hazel sewed on the first week = 4

Number of jackets that Hazel completed for from Tuesday to Sunday on the first week
= 4 x 7 + 2 x 14 
= 28 + 28
= 56

Number of jackets left to sew
= 131 - 56
= 75

Number of jackets that Hazel could sew per week from second week onwards
= 5 x 7 + 2 x 14
= 35 + 28
= 63

Number of weeks that Hazel needed to sew 75 jackets
= 75 ÷ 63
= 1 r 12

Number of days that Hazel needed to sew 12 jackets
= 12 ÷ 7
= 1 r 5

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

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

Answer(s): 2
