Sarah starts saving $5.00 a week for 4 weeks. Then she saves $10.00 a week for the next 4 weeks. Then she saves $20.00 a week for the next 4 weeks. How much money has she saved over 12 weeks?
Let's think: She starts with $5.00 a week for 4 weeks so that's 5 * 4 = $20.00. Then she bumps it up to $10.00 a week for 4 weeks so that's 10 * 4 = $40.00. After that, she saves $20.00 a week for 4 weeks so that's 20 * 4 = $80.00. Over 12 weeks she has saved 20 + 40 + 80 = $140.00.. The answer is: 140.

Hannah's family has ten pigs on their farm. They also have three fewer than twice as many cows as pigs and six more goats than cows. How many animals do they have on their farm?
Let's think: Twice the number of pigs is 10 x 2 = 20. So, Hannah's family has 20 - 3 = 17 cows. They also have 17 + 6 = 23 goats. So, they have a total of 10 + 17 + 23 = 50 animals on their farm.. The answer is: 50.

Granger went to the grocery store. He saw that the Spam is $3 per can, the peanut butter is $5 per jar, and the bread is $2 per loaf. If he bought 12 cans of spam, 3 jars of peanut butter, and 4 loaves of bread, how much is the total amount he paid?
Let's think: The 12 cans of Spam costs $3 x 12 = $36. The total amount of 3 jars of peanut butter is $5 x 3 = $15. And the total amount of the 4 loaves of bread is $2 x 4 = $8. Therefore the total amount he will have to pay is $36 + $15 + $8 = $59.. The answer is: 59.

From Monday to Friday, Elle practices piano for 30 minutes. On Saturday, she practices piano three times as much as on a weekday. There is no practice on Sunday. How many hours does Elle spend practicing piano each week?
Let's think:
From Monday to Friday, Elle practices 0.50 x 5 = 2.5 hours. On Saturday, she practices 0.50 x 3 = 1.5 hours. Each week, Elle practices piano for 2.5 + 1.5 = 4 hours.. The answer is: 4.
