Ivory had to sew 141 jumpsuits. She sewed 6 jumpsuits each day from Monday to Friday and 9 each day on Saturday and Sunday. Starting on a Wednesday, on which day of the week did Ivory finish sewing all the jumpsuits? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Ivory sewed on the first week = 3

Number of jumpsuits that Ivory completed for from Wednesday to Sunday on the first week
= 3 x 6 + 2 x 9 
= 18 + 18
= 36

Number of jumpsuits left to sew
= 141 - 36
= 105

Number of jumpsuits that Ivory could sew per week from second week onwards
= 5 x 6 + 2 x 9
= 30 + 18
= 48

Number of weeks that Ivory needed to sew 105 jumpsuits
= 105 ÷ 48
= 2 r 9

Number of days that Ivory needed to sew 9 jumpsuits
= 9 ÷ 6
= 1 r 3

Ivory needed 1 more day to finish sewing the remaining 3 jumpsuits.

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

Answer(s): 2
