Kimberly had to sew 109 dresses. She sewed 6 dresses each day from Monday to Friday and 10 each day on Saturday and Sunday. Starting on a Thursday, on which day of the week did Kimberly finish sewing all the dresses? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Kimberly sewed on the first week = 2

Number of dresses that Kimberly completed for from Thursday to Sunday on the first week
= 2 x 6 + 2 x 10 
= 12 + 20
= 32

Number of dresses left to sew
= 109 - 32
= 77

Number of dresses that Kimberly could sew per week from second week onwards
= 5 x 6 + 2 x 10
= 30 + 20
= 50

Number of weeks that Kimberly needed to sew 77 dresses
= 77 ÷ 50
= 1 r 27

Number of days that Kimberly needed to sew 27 dresses
= 27 ÷ 6
= 4 r 3

Kimberly needed 1 more day to finish sewing the remaining 3 dresses.

Day of the week that Kimberly completed her sewing
= 4 + 1
= 5 (Fri)

Answer(s): 5
