Wendy had to sew 232 blazers. She sewed 6 blazers each day from Monday to Friday and 13 each day on Saturday and Sunday. Starting on a Wednesday, on which day of the week did Wendy finish sewing all the blazers? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Wendy sewed on the first week = 3

Number of blazers that Wendy completed for from Wednesday to Sunday on the first week
= 3 x 6 + 2 x 13 
= 18 + 26
= 44

Number of blazers left to sew
= 232 - 44
= 188

Number of blazers that Wendy could sew per week from second week onwards
= 5 x 6 + 2 x 13
= 30 + 26
= 56

Number of weeks that Wendy needed to sew 188 blazers
= 188 ÷ 56
= 3 r 20

Number of days that Wendy needed to sew 20 blazers
= 20 ÷ 6
= 3 r 2

Wendy needed 1 more day to finish sewing the remaining 2 blazers.

Day of the week that Wendy completed her sewing
= 3 + 1
= 4 (Thu)

Answer(s): 4
