A basketball team played 40 games and won 70% of the games. It still had 10 games to play. How many games can they lose to win 60% of their games?

The team has won 40 x 70/100 =

<<40*70/100=28>>28 games out of 40. There a total of 40 + 10 = <<40+10=50>>50 games to be played. The team has to win a total of is 50 x 60/100 = <<50*60/100=30>>30 games. So, it still needs to win 30 - 28 = <<30-28=2>>2 more games. Hence, they can still lose 10 - 2 = <<10-2=8>>8 games. #### 8 A pet store owner had 12 birds, 9 puppies, 5 cats, and 15 spiders. Half the birds were sold and 3 puppies were adopted. Then, someone left the spider enclosure open and 7 of them went loose. How many animals does the pet store owner have left? There are 12/2 = <<12/2=6>>6 birds left. There are 9-3= <<9-3=6>>6 puppies left. There are 15 - 7 = <<15-7=8>>8 spiders left. The pet store owner has 5+6 + 6 + 8 = <<5+6+6+8=25>>25 animals left #### 25 Daytona Beach has 26 shark sightings a year. Daytona Beach has 5 more than triple the number of shark sightings as Cape May. How many shark sightings are there in Cape May? Let x be the number of shark sightings in Cape May 26=5+3x 21=3x x=<<7=7>>7 #### 7 The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received. When Kendra bought 2 toys, she paid 2*$20 = $<<2*20=40>>40 Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3*$10 = $<<3*10=30>>30 The total costs for the hats and wooden toys Kendra bought is $40+$30 = $<<40+30=70>>70 From the $100 bill, Kendra received change worth $100-$70 =$<<100-70=30>>30 #### 30 Michael has two brothers. His oldest brother is 1 year older than twice Michael's age when Michael was a year younger. His younger brother is 5 years old, which is a third of the age of the older brother. What is their combined age? The oldest brother is 15 because 3 x 5 = <<3*5=15>>15 Michael is 8 because if 1 + (Michael's age - 1) x 2 = 15 then Michael's age = 8 Their combined age is 28 because 5 + 15 + 8 = <<5+15+8=28>>28 #### 28 Daria wants to go to a concert by her favorite band. She wants to buy tickets for her and for three of her friends. One ticket cost is $90. How much money does Daria need to earn if she currently has only $189? Daria wants to buy tickets for four persons, so the cost will be 4 tickets * $90/ticket = $<<4*90=360>>360. Daria currently has $189, so she needs $360 - $189 = $<<360-189=171>>171 more. #### 171 Jane's mother agreed to pay her $.50 for every flower bulb that Jane planted. Jane planted 20 tulip bulbs and half that amount of iris bulbs. She also planted 30 daffodil bulbs and three times that amount of crocus bulbs. How much money did Jane earn? 20 tulip bulbs at $.50 each is 20*.50 $<<20*.50=10>>10.00 She planted half that amount of iris' so 20/2= <<20/2=10>>10 bulbs 10 iris bulbs at $.50 each is 10* .50 = $<<10*.50=5.00>>5.00 30 daffodil bulbs at $.50 each is 30*.50=$<<30*.50=15.00>>15.00 She planted three times that amount of crocus bulbs to 30*3 = <<30*3=90>>90 bulbs 90 crocus bulbs at $.50 = $<<90*.50=45.00>>45.00 All total, she earned 10+5+15+45 = $<<10+5+15+45=75.00>>75.00 #### 75 In a city, the number of people living per cubic yard is 80. How many more people are in a city with 9000 cubic yards than a city with 6400 cubic yards? The difference in cubic yards between the two cities is 9000-6400 = <<9000-6400=2600>>2600 cubic yards. Since the number of people living in a city per cubic yard is 80, there are 80*2600 = 208000 more people living in a city with 9000 cubic yards than a city with 6400 cubic yards. #### 208000 There are 480 grains of rice in one cup. If half a cup is 8 tablespoons and one tablespoon is 3 teaspoons, how many grains of rice are in a teaspoon? First find the number of tablespoons in a full cup: 8 tablespoons/half-cup * 2 half-cups/cup = <<8*2=16>>16 tablespoons Then find the total number of teaspoons in a cup: 16 tablespoons/cup * 3 teaspoons/tablespoon = <<16*3=48>>48 teaspoons Then find the number of grains of rice per teaspoon: 480 grains / 48 teaspoons = <<480/48=10>>10 grains/teaspoon #### 10 Mandy started reading books with only 8 pages when she was 6 years old. By the time she was twice that age, she was reading books 5 times longer, and 8 years later, she was reading books 3 times longer than that. Presently, she reads books that are 4 times the previous length. How many pages do the books she reads now have? Twice the age of 6 is 6 x 2 = <<6*2=12>>12 years old. At 12 years old, Mandy was reading books 5 x 8 = <<5*8=40>>40 pages long. 8 years later, Mandy was 12 + 8 = <<12+8=20>>20 years old. At 20 years old, Mandy was reading books 3 x 40 = <<3*40=120>>120 pages long. Presently, she reads books that are 120 x 4 = <<120*4=480>>480 pages long. #### 480
