Cindy was 5 years old. Her sister Jan was 2 years older than Cindy. Their oldest sister Marcia was twice as old as Jan. Greg was two years older than Marcia. How old was Greg?

Jan was 2 years older than Cindy who was 5 so 2+5 =

<<2+5=7>>7 years old Marica was twice as old as Jan so 2*7 = <<2*7=14>>14 years old Greg was 2 years older than Marcia who was 14 so 2+14 = <<2+14=16>>16 years old #### 16 Johnny TV makes 25 percent more movies than L&J Productions each year.

She makes square biscuits and each biscuit is 3 inches by 3 inches. How many biscuits can she make with this dough? She has 144 square inches of dough because 12 times 12 equals <<12*12=144>>144. Each biscuit uses 9 square inches of dough because 3 times 3 equals 9. She can make 16 biscuits because 144 divided by 9 equals <<144/9=16>>16. #### 16 Oleg is an event organizer. He is organizing an event with 80 guests where 40 of them are men, half the number of men are women, and the rest are children. If he added 10 children to the guest list, how many children will there be at the event? There are 40/2= <<40/2=20>>20 women at the event. Hence, there are a total of 40 + 20 = <<40+20=60>>60 men and women at the event. So, the total number of children at the event is 80 - 60 = <<80-60=20>>20. After Oleg added 10 children to the guest list, there are a total of 20 + 10 = <<20+10=30>>30 children. #### 30 Kevin holds the world record for eating the biggest quantity of hot wings in 8 minutes. He can eat 64 wings without stopping. Alan, a boy who loves hot wings, wants to beat Kevin's record. He is currently able to eat 5 hot wings per minute. How many more wings must he eat per minute to beat Kevin's record? Knowing Kevin's record of eating 70 wings in 8 minutes or 64 / 8 = 8 wings in a minute Alan must increase his ability to eat 5 wings per minute to 8 - 5 = 3 wings per minute to equal Kevin's world record. To beat Kevin, Alan must eat 3+1 = <<3+1=4>>4 hot wings per minute. #### 4 Sarah, Mary, and Tuan decided to go to the restaurant for a meal. They decided to split the cost of the meal evenly. If the total price of the meal comes to $67 and they have a coupon for $4, how much does each person need to contribute to the bill?

If both parties combined had 240 people, how many people were there at Ryan's party? To get the number of people at Taylor's party, we'll assume there were n people at his party. The total number of people at Ryan's party is 4*n, four times the number of attendees at Taylor's party. Combined, there were 4n+n = 240 people at both parties. This translates to 5n=240. The total number of people at Taylor's party is n=240/5 There were n=<<48=48>>48 people at Taylor's party. Since Ryan's party was 4 times as huge as Taylor's party, at Ryan's party, there were 48*4 = <<48*4=192>>192 people. #### 192 In one hour, Addison mountain's temperature will decrease to 3/4 of its temperature. If the current temperature of the mountain is 84 degrees, what will the temperature decrease by? In one hour, Addison mountain's temperature will decrease to 3/4 of the temperature it is now, meaning the temperature will decrease to 3/4*84=<<3/4*84=63>>63 degrees. The temperature decrease will be 84-63=<<84-63=21>>21 degrees #### 21 Mary has 26 blue shirts and 36 brown shirts. If she gives away half of her blue shirts and a third of her brown shirts, how many shirts does she have left? Mary gives away 26/2 = <<26/2=13>>13 blue shirts. Mary gives away 36/3 = <<36/3=12>>12 brown shirts. Mary has 26-13 = <<26-13=13>>13 blue shirts left. Mary has 36-12 = <<36-12=24>>24 brown shirts left.
