First, the shop is open 12 hours * 60 minutes = 720 minutes per day. So, 720 / 30 = 24 women's T - shirts sold per day. The shop earns 24 * $18 = $432 selling women's T - shirts per day. Similarly, 720 / 40 = 18 men's T - shirts are sold per day. The shop earns 18 * $15 = $270 selling men's T - shirts per day. The shop earns $432 + $270 = $702 per day selling T - shirts. The shop earns $702 * 7 = $4914 per week.
The answer: 4914

Reasoning and answer: Of the colored paper, Barbara removed 3 * 2 = 6 sheets of paper. Of the white paper, she removed 2 * 4 = 8 sheets of paper. Of the scrap paper, she removed 5 * 20 = 100 sheets of paper. So in total, Barbara removed 6 + 8 + 100 = 114 sheets of paper.
The answer: 114

She'll be on vacation for 40 days and drinks 3 cups of coffee / pods per day for a total of 40 * 3 = 120 coffee pods. Her coffee pods come 30 in a box and she needs 120 coffee pods so that’s 120 / 30 = 4 boxes. Each box costs $8.00 and she needs 4 boxes so that’s 8 * 4 = $32.00.
The answer: 32

Reasoning and answer: 900 x 3 / 4 = 675 people came before the start of the concert. 900 - 675 = 225 people did not come before the start of the concert. 225 x 5 / 9 = 125 people came few minutes after the first song. So, 125 + 80 = 205 people came to the concert that was not able to be at the start of the concert. Therefore, 225 - 205 = 20 people did not go to the concert.
The answer: 20
