Mason is three times younger than Sydney and Sydney is six years younger than Mason's father. If Mason is 20 years old, how old is his father?

Sydney is 20*3 =

<<20*3=60>>60 years old. Mason’s father is 60+6 = <<60+6=66>>66 years old. #### 66 Bill is doing weight training before trying out for the boxing team. He gets two 2-gallon jugs and fills them 70% full with sand. If sand has a density of 5 pounds/gallon, how many pounds do Bill's improvised weights weigh? First find the volume of the sand in one jug: 2 gallons * 70% = <<2*70*.01=1.4>>1.4 gallons Then double this amount since there are two jugs: 1.4 gallons * 2 = <<1.4*2=2.8>>2.8 gallons Then multiply the total volume by the density of sand to find the total weight: 2.8 gallons * 5 pounds/gallon = <<2.8*5=14>>14 pounds #### 14 Quincy just bought a car using a 5 year loan with no interest. He put $5,000.00 down as a down payment making his monthly payment $250.00. What is the price of the car? 1 year has 12 months and his loan is for 5 years so that's 12*5 = <<12*5=60>>60 months His car payment is $250.00 a month for 60 months so 250*60 = $<<250*60=15000>>15,000 He also put a down payment of $5,000 on the car so the total price of the car is $5,000 + $15,000 = $<<5000+15000=20000>>20,000 car price #### 20000 Marites internet speed is 10 megabits per second and her monthly internet bill is $20. Marites is planning to upgrade her service and choosing between 20 Mbps and 30 Mbps. If the price of the 30 Mbps is twice the amount of her current monthly bill and the price of the 20 Mbps is $10 more than her current monthly bill, how much will she save per year if she chooses the 20 Mbps than 30 Mbps? The total monthly bill for 30 Mbps is $20 x 2= $<<20*2=40>>40. She will have to pay $40 x 12 = $<<40*12=480>>480 every year for 30mbps. The total monthly bill for 20 Mbps is $20 + $10= $<<20+10=30>>30. So, she will have to pay $30 x 12 = $<<30*12=360>>360 for 20 Mbps per year. Therefore the amount she will save per year if she chooses the 20mbps is $480 - $360 = $<<480-360=120>>120 #### 120 Tony loved to solve difficult pen and paper puzzles. He did a warm-up puzzle that only took 10 minutes and after that he did 2 puzzles that each took 3 times as long. How long did he spend solving puzzles? Each of the long puzzles took 3*10=<<3*10=30>>30 minutes to solve So he spent 30*2=<<30*2=60>>60 minutes solving them That means he spent 60+10=<<60+10=70>>70 minutes solving puzzles #### 70 Jordan is a hockey goalie. In the first period of a game, he blocked four shots. In the second period, he blocked twice as many shots. In the third period, he blocked three fewer than in the second period. When the game ended after the fourth period, he had blocked 21 shots in all. How many did Jordan block in the fourth period? Let F be the number of shots Jordan blocked in the fourth period. In the second period, he blocked 2 * 4 = <<2*4=8>>8 shots. In the third period, he blocked 8 - 3 = <<8-3=5>>5 shots. In the whole game, he blocked 4 + 8 + 5 + F = 17 + F = 21 shots. Thus, Jordan blocked F = 21 - 17 = <<21-17=4>>4 shots in the fourth period. #### 4 Thomas has been saving $40 in the bank every month for six years. His friend Joseph has been saving 2/5 times less money per month. How much money are they having in their savings account altogether? Thomas has been saving for six years, and since each year has 12 months, he has been making savings for 6*12 = <<6*12=72>>72 months. Since Thomas has been saving $40 in the bank every month for six years, he has saved 72*$40 = $<<72*40=2880>>2880 Joseph has been saving 2/5 times less money per month than Thomas, meaning he has been saving 2/5*$40 = $<<2/5*40=16>>16 less per month. The total amount of money that Joseph has been saving per month is $40-$16 = $<<40-16=24>>24 In six years, Joseph has saved $24*72 = $<<24*72=1728>>1728 Together, they have saved a total of $2880+$1728 = $<<2880+1728=4608>>4608 #### 4608 When Jack traveled to Canada, he had to wait 20 hours to get through customs, plus 14 days in coronavirus quarantine. How many hours total did Jack have to wait? First convert the quarantine wait time to hours by multiplying the number of days by the number of hours in a day: 14 days * 24 hours/day = <<14*24=336>>336 hours Then add the time Jack spent waiting in customs to the quarantine time: 336 hours + 20 hours = <<336+20=356>>356 hours #### 356 Jesse is desperately trying to finish a book for a school book report due on Monday so he can play this weekend. Friday afternoon, he read the first 5 chapters, which were 10, 15, 27, 12, and 19 pages, respectively, before taking a break. To his dismay, he found that he was only 1/3 of the way through the book. How many pages does he still have to read? So far, Jesse has read 10 + 15 + 27 + 12 + 19 = <<10+15+27+12+19=83>>83 pages. That's 1/3 of the book, so the remainder of the book is twice as many pages, or 2 * 83 = 166 pages. #### 166 Leila eats cake almost every week. Last week, she ate 6 cakes on Monday, 9 cakes on Friday, and on Saturday, she ate triple the number of cakes she ate on Monday. How many cakes does Leila eat? Combining Monday and Friday, Leila ate 6 + 9 = <<6+9=15>>15 cakes. On Saturday, she ate 6 * 3 = <<6*3=18>>18 cakes. Altogether, Leila ate 15 + 18 = <<15+18=33>>33 cakes. #### 33
