Cordelia is dyeing her hair red. To get the color she wants, she first has to bleach her dark brown hair to blonde, and then she has to apply the dye. The whole process will take 9 hours. Dyeing takes twice as long as bleaching. How many hours will it take Cordelia to bleach her hair?
Let's think: Let H be the number of hours it takes Cordelia to bleach her hair. A dye treatment takes twice as long, so it takes 2H. Thus, bleaching and dying will take H + 2H = 3H = 9 hours. Therefore, it will take Cordelia H = 9 / 3 = 3 hours to bleach her hair.. The answer is: 3.

Owen bought 12 boxes of face masks that cost $9 per box. Each box has 50 pieces of masks. He repacked 6 of these boxes and sold them for $5 per 25 pieces. He sold the remaining 300 face masks in baggies at the rate of 10 pieces of mask for $3. How much profit did he make?
Let's think: Owen bought 12 boxes for a total of $9 / box x 12 boxes = $108. Six boxes contains 6 boxes x 50 masks / box = 300 face masks. Owen made 300 masks / 25 masks / repack = 12 repacks. So, his revenue for selling those repacked face masks is $5 x 12 repacks = $60. There are 300 masks / 10 masks / baggy = 30 baggies face masks. So, his revenue for that is $3 / baggy x 30 baggies = $90. Hence, his total revenue for all the face masks is $60 + $90 = $150. This gives him a profit of $150 - $108 = $42.. The answer is: 42.

Ral is twice as old as Suri. In 3 years, Suri's current age will be 16. What is Ral's current age?
Let's think: If Suri will be 16 in 3 years, that means she is 16 - 3 = 13 years old now. Rai is twice as old as Suri, so she is 2 * 13 = 26 years old now.. The answer is: 26.

The P.T.O. decided to provide shirts for the elementary students for track and field day. Each grade was given a different color. 101 Kindergartners wore orange shirts that cost $5.80 each. 113 first graders wore yellow shirts that cost $5 each. 107 second graders wore blue shirts that cost $5.60 each. 108 third graders wore green shirts that cost $5.25 each. How much did the P.T.O. spend on shirts for field day?
Let's think:
The cost for 101 Kindergarten shirts x $5.80 = $585.80. The cost for 113 first grade shirts x $5 = $565. The cost for 107 second grade shirts x $5.60 = $599.20. The cost for 108 third grade shirts x $5.25 = $567. The total cost of the shirts was $585.80 + $565 + $599.20 + $567 = $2,317.. The answer is: 2317.
