Lloyd, Mark, and Michael have their Pokemon cards collection. Currently, Mark has thrice as many cards as Lloyd but has 10 fewer cards than Michael. If Michael has 100 cards now, how many more cards should they collect so that all three of them will have a total of 300 cards?

Mark has 10 fewer cards than Michael so Mark has 100 cards - 10 cards = 90 cards.

So, Lloyd has 90 cards / 3 =

<<90/3=30>>30 cards. All three of them have 90 cards + 30 cards + 100 cards = <<90+30+100=220>>220 cards. Thus, they need to collect 300 cards - 220 cards = <<300-220=80>>80 more cards. #### 80 Jean has 3 grandchildren. She buys each grandkid 2 cards a year and puts $80 in each card. How much does she give away to grandchildren a year? Each grandchild gets 2*80=$<<2*80=160>>160 a year So that means they get a total of 3*160=$<<3*160=480>>480 #### 480 While Paul watches movies, he runs on his treadmill. He can run a mile in 12 minutes. He watches two movies, which are an average length of 1.5 hours. How many miles does he run? He runs for 3 hours because 2 x 1.5 = <<2*1.5=3>>3 He runs for 180 minutes because 3 x 60 = <<3*60=180>>180 He runs 15 miles because 180 / 12 = <<180/12=15>>15 #### 15 Javier is selling donuts to raise money for a new game. He wants to raise $96. He buys each dozen donuts for $2.40 and then sells each donut for $1. How many dozen donuts does he need to buy and sell to reach his goal? Every donut costs him $.2 because 2.4 divided by 12 equals <<2.4/12=.2>>.2 So he makes $.8 for every donut he sells because $1 minus $.2 equals .8 He needs to sell 120 donuts because 96 divided by .8 equals <<96/.8=120>>120. He needs to buy and sell 10 dozen donuts because 120 divided by 12 equals <<120/12=10>>10 #### 10 Kylie has 5 daisies. Her sister gave her another 9 daisies. Kylie then gave half her daisies to her mother. How many daisies does Kylie have left? Kylie had 5 + 9 = <<5+9=14>>14 daisies. She has 14/2 = <<14/2=7>>7 daisies left. #### 7 Jon buys 2 coffees a day from his favorite coffee shop. They cost $2 each. How much does he spend in April? He spends 2*$2=$<<2*2=4>>4 per day April has 30 days so he spends $4*30=$<<4*30=120>>120 #### 120 Ruby is taking dance lessons. They cost $75 for 10 classes in one pack. She can add additional classes at the price of 1/3 more than the average price of a class on the lesson in the pack. if she takes 13 total classes, how much does she pay? The classes in the pack cost $7.5 each because 75 / 10 = <<75/10=7.5>>7.5 An additional class costs $10 because 7.5 x (1 +(1/3)) = <<7.5*(1+(1/3))=10>>10 She buys 3 extra classes because 13 - 10 = <<13-10=3>>3 Her three additional classes cost $30 because 3 x 10 = <<3*10=30>>30 Her total cost is $105 because 75 + 30 = <<75+30=105>>105 #### 105 Johnny has been playing guitar for a while now. He practices the same amount each day. As of 20 days ago he had half as much practice as he has currently. How many days will pass before Johnny has 3 times as much practice as he does currently? If Johnny had half as much practice as he currently has as of 20 days ago, this means he has 20*2=<<20*2=40>>40 days worth of practice currently. Therefore, to have three times as much practice as he currently has, he'd need to practice for 40*3=<<40*3=120>>120 days. Since he's already practiced for 40 days, this means he needs to practice or 120-40= <<120-40=80>>80 more days #### 80 Jason goes to the library 4 times more often than William goes. If William goes 2 times per week to the library, how many times does Jason go to the library in 4 weeks? The number of times Jason goes to the library per week is 4 * 2 = <<4*2=8>>8 times. The number of times he goes to the library in 4 weeks is 8 * 4 = <<8*4=32>>32 times. #### 32 Wanda weighs 30 pounds more than Yola currently. Wanda also weighs 80 pounds more than Yola did 2 years ago. How much did Yola weigh 2 years ago if she currently weighs 220 pounds? If Yola currently weighs 220 pounds, then Wanda, who weighs 30 pounds more than Yola, weighs 220+30 = <<220+30=250>>250 pounds. Wanda also weighs 80 pounds more than Yola did 2 years ago, meaning Yola weighed 250-80=<<250-80=170>>170 pounds 2 years ago. #### 170
