The number of coronavirus cases in a certain country was 300 infections per day during the first wave. However, the number of cases increased by four times more per day as a new coronavirus variant started infecting people in a second wave. What was the total number of infections during the second wave in 2 weeks?

When the number of cases increased by four times more per day during the second wave, there were 4*300 =

<<4*300=1200>>1200 more infections per day than during the first wave. The total number of infections during the second wave per day was 1200+300=<<1200+300=1500>>1500 For two weeks with 14 days, the number of me infections was 14*1500=<<14*1500=21000>>21000 #### 21000 At a convention, 16 of 36 delegates arrived with pre-printed name badges. Half of the remaining delegates made their own, hand-written name badges. How many delegates were not wearing name badges? There were 36-16=<<36-16=20>>20 without pre-printed name badges. Then 20/2=<<20/2=10>>10 made hand-written badges There were 20-10=<<20-10=10>>10 with no name badge. #### 10 Marta is arranging floral centerpieces for a reception party. Each arrangement needs to have 8 roses,12 daisies, 3 snapdragons and twice as many lilies. The reception will have 10 tables. How many flowers will she need in total to fill this order? She needs twice as many lilies as the 3 snapdragons in the arrangement so she needs 2*3 = <<2*3=6>>6 lilies She needs 8 roses, 12 daisies, 3 snapdragons and 6 lilies for a total of 8+12+3+6 = <<8+12+3+6=29>>29 flowers per arrangement She needs 29 flowers per each of the 10 tables for a total of 29*10 = <<29*10=290>>290 flowers #### 290 It takes Dawn 2 hours to paint 1 watercolor painting. She was recently commissioned to paint a series of 12 paintings. Dawn will earn $3,600.00 for these 12 paintings. How much money does Dawn make per hour? It takes her 2 hours to paint 1 picture and she needs to paint 12 pictures so it will take 2*12 = <<2*12=24>>24 hours Dawn will make $3,6000.00 for 24 hours of work which means she makes 3600/24 = $150.00 per hour of work #### 150 Joshua and Justin shared $40. Joshua’s share was thrice as much as Justin’s. How much is Joshua's share? The $40 is divided into 1 part for Justin + 3 parts for Joshua = 4 parts. So each part is equal to $40/4 = $<<40/4=10>>10. Therefore, Joshua's share is $10 x 3 = $<<10*3=30>>30. #### 30 Mary and her two friends came up with the idea of collecting marbles each day for their play on weekends. From Monday to Friday, Mary collected twice as many red marbles as Jenny and half the number of blue marbles collected by Anie, who collected 20 more red marbles than Mary and twice the number of blue marbles Jenny collected. If Jenny collected 30 red marbles and 25 blue marbles, what's the total number of blue marbles collected by the friends together? If Mary collected twice the number of red marbles collected by Jenny, she got 2*30 = <<2*30=60>>60 red marbles. Anie collected 20 more red marbles than Mary, which is 60+20 = 80 red marbles. The total number of red marbles is 60+80+30 = <<60+80+30=170>>170 red marbles. If Anie collected twice the number of blue marbles collected by Jenny, then she got 2*25 = <<2*25=50>>50 blue marbles. Mary collected half the number of blue marbles collected by Anie, thus 1/2*50 = 25 marbles The total number of blue marbles collected is 50+25+25 = <<50+25+25=100>>100 blue marbles #### 100 Dennis collected 10 rocks. He put all of them in his aquarium but his fish ate half of them. He was able to make the fish spit two out. How many of Dennis's rocks are left? Dennis had 10/2=<<10/2=5>>5 rocks left after the fish ate them. He made the fish spit two out, which left Dennis with 5+2=<<5+2=7>>7 rocks. #### 7 John buys 3 t-shirts that cost $20 each. He also buys $50 in pants. How much does he spend? He spends 20*3=$<<20*3=60>>60 on t-shirts So he spends 60+50=$<<60+50=110>>110 in total #### 110 John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now? He lost 500*.8=<<500*.8=400>>400 pounds from his bench So his bench went to 500-400=<<500-400=100>>100 pounds After training it increased to 100*3=<<100*3=300>>300 pounds #### 300 Silvia wants to buy a new guitar online. The price of the guitar has a suggested retail price of $1000. Guitar Center has a special deal of 15% off but has a shipping fee of $100. Sweetwater has a 10% off deal with free shipping. How much will she save by buying from the cheaper store compared to the other store? The discount saved when buying from Guitar Center would be $1000 * 15% = $<<1000*15*.01=150>>150. The total cost when buying from Guitar Center would be $1000 - $150 discount + $100 shipping = $950. The discount when buying from Sweetwater would be $1000 * 10% = $<<1000*10*.01=100>>100. The total cost when buying from Sweetwater would be $1000 - $100 discount + $0 shipping = $<<1000-100-0=900>>900. Thus, Silvia would save $950 - $900 = $<<950-900=50>>50 when buying from Sweetwater. #### 50
