Lynn had to sew 260 dresses. She sewed 8 dresses each day from Monday to Friday and 12 each day on Saturday and Sunday. Starting on a Tuesday, on which day of the week did Lynn finish sewing all the dresses? Give your answer in number. (Eg Mon = 1)
Number of weekdays that Lynn sewed on the first week = 4

Number of dresses that Lynn completed for from Tuesday to Sunday on the first week
= 4 x 8 + 2 x 12 
= 32 + 24
= 56

Number of dresses left to sew
= 260 - 56
= 204

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

Number of weeks that Lynn needed to sew 204 dresses
= 204 ÷ 64
= 3 r 12

Number of days that Lynn needed to sew 12 dresses
= 12 ÷ 8
= 1 r 4

Lynn needed 1 more day to finish sewing the remaining 4 dresses.

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

Answer(s): 2
