If Jessica's mother would be alive today, ten years later after her death, she would be 70, meaning she died at 70-10=

<<60=60>>60 If Jessica was half her mother's age when her mother died, she was 1/2*60=30 years old. Currently, ten years later, Jessica is 10+30=<<10+30=40>>40 years old. #### 40 Tommy is making steaks for his family. There are 5 of them in total. If each member wants one pound and the steaks are 20 ounces each, how many does he need to buy? He needs 80 ounces of steak because 5 x 16 = <<5*16=80>>80 He need 4 steaks because 80 / 20 = <<80/20=4>>4 #### 4 There are 9 boys and 12 girls in a class. The teacher needs to create groups with three members for their class activity. How many groups are formed? There are 9 + 12 = <<9+12=21>>21 students in a class. Hence, 21/3 = <<21/3=7>>7 groups are formed. #### 7 In twenty years, Ramon will be twice as old as Loui today. If Loui is currently 23 years old, how old is Ramon now? If Loui is currently 23 years old, twice her age, which is the same as twice Ramon's age in twenty years, is 23*2=<<23*2=46>>46 If in twenty years Ramon will be 46, currently he is 46-20= <<46-20=26>>26 years old. #### 26 Bob has a cube of silver that measures 3 inches on each side. A cubic inch of silver weighs 6 ounces. Each ounce of silver sells for $25. He sells it for 110% of its silver value. How much does he sell it for? The silver has a volume of 3*3*3=<<3*3*3=27>>27 cubic inches So it weighs 27*6=<<27*6=162>>162 ounces So its value is 162*25=$<<162*25=4050>>4050 That means he sold it for 4050*1.1=$<<4050*1.1=4455>>4455 #### 4455 There are 80 passengers on the airplane where the number of men and women is equal. The rest of the passengers are children. How many children are on the airplane if there are 30 men? Since the number of men and women is equal, then there are a total of 30 + 30 = <<30+30=60>>60 men and women. Thus, 80 - 60 = <<80-60=20>>20 children are on the airplane. #### 20 Jose threatened to withhold 20% of Amanda's pay if she does not finish her sales report by midnight. If Amanda makes $50.00 an hour and works for 10 hours a day, how much money will she receive if she does not finish the sales report by midnight? If she works for 10 hours a day at an hourly pay of $50, then her total income in a day is $<<10*50=500>>500. If she doesn't meet the deadline Jose gave her, she'll lose 20/100*$500 = $<<20/100*500=100>>100 She'll receive $500-$100= $<<500-100=400>>400 if Jose cuts out 20% of her pay. #### 400 Yella's computer usage last week was 91 hours. If she plans to use the computer 8 hours a day for this week, how much less ​is her computer usage for this week? Yella can use the computer 8 x 7 = <<8*7=56>>56 hours for this week. Therefore, Yella's computer usage for this week is 91 - 56 = <<91-56=35>>35 hours lesser than her computer usage last week. #### 35 Teresa is 59 and her husband Morio is 71 years old. Their daughter, Michiko was born when Morio was 38. How old was Teresa when she gave birth to Michiko? The difference in age between Teresa and Morio is 71 - 59 = <<71-59=12>>12 years. When their daughter is born, Teresa is 38 - 12 = <<38-12=26>>26 years old. #### 26
