Last night Kannon had 3 apples, a banana, and 4 oranges for dinner. Today she is planning to have 4 more apples than last night, 10 times as many bananas as she ate last night, and twice as many oranges as apples she'll have today. How many fruits would she have eaten so far in the two meals? Give the rationale and then the answer.
Let's think step by step. The total number of fruits that Kannon ate last is 3 apples + 1 banana + 4 oranges = 8. Since last night Kannon had 3 apples, today she'll eat 3 + 4 = 7 apples. She is also planning to eat 10 times as many bananas as she ate last night, a total of 1 * 10 = 10 bananas. Kannon will also eat twice as many oranges as apples she'll have today, which means she'll eat 7 * 2 = 14 oranges. Tonight Kannon will eat 14 oranges + 10 bananas + 7 apples = 31 fruits. In total, after tonight, Kannon would have eaten 31 + 8 = 39 fruits.. The answer is: 39.

Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50 and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase? Give the rationale and then the answer.
Let's think step by step. 5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00.. The answer is: 23.

Jude bought three chairs for his house, all at the same price. He also bought a table that costs $50 and two sets of plates at $20 for each set. After giving the cashier $130, Jude got a $4 change. How much did each of the chairs cost? Give the rationale and then the answer.
Let's think step by step. The two sets of plates amount to $20 x 2 = $40. So the table and the two sets of plates amount to $50 + $40 = $90 in all. Since Jude received a $4 change, then he paid a total of $130 - $4 = $126 for the chairs, tables, and plates. Thus, the three chairs cost $126 - $90 = $36. Therefore, each chair cost $36 / 3 = $12.. The answer is: 12.
