question:Maya has 240 cents in dimes. Maya gives 40 cents to Olivia and three times as many cents to Ava as she gave to Olivia. How many more dimes does Ava have than Olivia?
answer:Maya gives Olivia 40 cents and Ava three times as many, which is 3 * 40 = 120 cents.Since each dime is 10 cents, Olivia has 40 / 10 = 4 dimes and Ava has 120 / 10 = 12 dimes.The difference between the number of dimes Ava and Olivia have is 12 - 4 = 8.Thus, Ava has boxed{8} more dimes than Olivia.
question:Ethan earned a total profit of 56 this month. His pet-sitting business brought in 70, and he also sold handmade crafts for 25. However, running the pet-sitting business requires expenses for food, toys, and supplies. How much did Ethan spend on operating his pet-sitting business, in dollars?
answer:Let's denote the expenses for operating the pet-sitting business as x.Ethan's total profit is 56, which is the sum of his revenues from pet-sitting (70) and handmade crafts (25) minus the expenses of pet-sitting (x).So the equation becomes 56 = 70 + 25 - x, which implies 56 = 95 - x.Rearranging this equation, we get x = 95 - 56.Thus, x = 39.So Ethan spent boxed{39} dollars on operating his pet-sitting business.
question:Alex has 5 bicycles. The silver one can travel at three times the speed of the black one, but the black one can travel at 4 times the speed of the purple one. The orange one has a flat tire and cannot be ridden. The white one can travel at the same speed as the black one. If the purple one can travel at a speed of 12 miles per hour, at what speed, in miles per hour, can the silver bicycle travel?
answer:Let's break down the information:* The purple bicycle travels at 12 miles per hour.* The black bicycle travels at 4 times the speed of the purple one, which is 4 * 12 = 48 miles per hour.* The white bicycle travels at the same speed as the black one, which is also 48 miles per hour.* The silver bicycle travels at 3 times the speed of the black one, which is 3 * 48 = 144 miles per hour.So, the silver bicycle can travel at boxed{144} miles per hour.
question:Bert bought some unique stamps for his collection. Before the purchase, he had only half the stamps he bought. If he bought 300 stamps, how many stamps does Bert have in total after the purchase?
answer:Let's break it down:Bert bought 300 stamps.Before the purchase, he had only half the stamps he bought, which means he had 300 / 2 = 150 stamps.Now, after the purchase, he has the 150 stamps he already had, plus the 300 stamps he bought.So, the total number of stamps Bert has after the purchase is 150 + 300 = 450.Thus, Bert has boxed{450} stamps in total after the purchase.
question:Emily and Ryan are planning to buy a new bike that costs 900. They decided that Ryan would contribute 25% of the cost. How much does Emily need to pay to cover the remaining amount?
answer:Ryan will contribute 25% of the cost of the bike, which is 900 * 25 / 100 = 22500 / 100 = 225.So Emily needs to cover the remaining amount, which is 900 - 225 = 675.Thus, Emily needs to pay boxed{675} dollars.
question:Tom bakes a batch of cookies for his family. He eats 4 cookies on Wednesday and three times as many on Thursday. After he has eaten the cookies on Thursday, all of the cookies he baked are gone. How many cookies did Tom bake?
answer:Let's denote the total number of cookies Tom baked as x.Tom eats 4 cookies on Wednesday.He eats three times as many cookies on Thursday, which means he eats 3 * 4 = 12 cookies on Thursday.So, the total number of cookies he ate is 4 + 12 = 16.Since he ate all the cookies he baked, the total number of cookies he baked, x, is equal to the total number of cookies he ate, which is 16.Thus, Tom baked boxed{16} cookies.
