Answer this question:Miriam has five times as many albums as Katrina. Katrina has six times the number of albums as Bridget. Bridget has 15 fewer albums than Adele. How many albums do they have together if Adele has 30 albums?
Since Adele has 30 albums, and Bridget has 15 fewer, Bridget has 30 - 15 = 15 albums. Together, Bridget and Adele has 30 + 15 = 45 albums. Katrina has six times the number of albums as Bridget, a total of 15 * 6 = 90 albums. Adele, Bridget, and Katrina have a total of 90 + 45 = 135 albums together. Miriam has five times the number of albums as Katrina, a total of 5 * 90 = 450 albums. Together, Adele, Bridget, Katrina, and Miriam have 135 + 450 = 585 albums.
The answer is 585.

Answer this question:Jenny brought in 40 peanut butter cookies and 50 chocolate chip cookies for the bake sale. Marcus brought in 30 peanut butter cookies and and 20 lemon cookies. If Renee, who's allergic to peanuts, picks a cookie at random, what is the chance she'll have an allergic reaction expressed as a percentage?
First find the total number of peanut butter cookies: 40 peanut butter cookies + 30 peanut butter cookies = 70 peanut butter cookies. Then find the total number of cookies by adding the number of peanut butter cookies to the number of the other two types: 70 peanut butter cookies + 50 chocolate chip cookies + 20 lemon cookies = 140 cookies. Then divide the number of peanut butter cookies by the total number of cookies and multiply by 100% to find the percentage chance of Renee getting a peanut butter cookie: 70 peanut butter cookies / 140 cookies * 100% = 50%.
The answer is 50.

Answer this question:Amanda has to sell 80 tickets in 3 days so she can make enough money to go on vacation. On the first day, she sells 5 of her friends 4 tickets each. On the second day she sells 32 tickets. How many tickets does she need to sell on the third day to meet her goal?
Amanda sells 4 tickets to 5 friends so she sells 4 * 5 = 20 tickets on her first day. On her second day, she sells 32 tickets for a total of 20 + 32 = 52 Tickets so far. Having 80 tickets as the goal, she needs to sell 80 - 52 = 28 Tickets on her last day.
The answer is 28.

Answer this question:Aria has twice as many high school credits as Emily, who has twice the number of high school credits as Spencer. If Emily has 20 credits, what's twice the total number of high school credits the three have?
If Emily has 20 credits, and Aria has 2 times as many, then Aria has 2 * 20 = 40 high school credits. Emily has twice the number of high school credits Spencer has, meaning Spencer has 20 / 2 = 10 high school credits. Altogether, the three have 40 + 20 + 10 = 70 high school credits. Twice the total number of high school credits the three have is 2 * 70 = 140.
The answer is 140.
