From his apartment, Kona drives 9 miles to the bakery. From there, he drives 24 miles to his grandmother’s house. From her house, he drives 27 miles straight to his apartment. How many additional miles did Kona drive round trip to the bakery stop, compared to a round trip without the bakery stop? Give the rationale and then the answer.
Let's think step by step. With the bakery stop, Kona drove a total of 9 + 24 + 27 = 60 miles. Without the bakery stop, Kona drove a total of 27 + 27 = 54 miles. With the bakery stop, Kona drives an additional 60 - 54 = 6 miles.. The answer is: 6.

Jane brings 75% as many pieces of bread as treats to feed the live pets at the zoo. Wanda brings half as many treats as Jane and three times as many pieces of bread as treats. If Wanda brings 90 pieces of bread, what is the total number of pieces of bread and treats that Wanda and Jane brought to the zoo? Give the rationale and then the answer.
Let's think step by step. Wanda brought 90 pieces of bread, three times the number of treats, so Wanda brought 90 / 3 = 30 treats. Wanda brought half as many treats as Jane, which means Jane brought 30 * 2 = 60 treats. The total number of pieces of bread Jane brought is 75% of the number of treats, which means Jane brought 0.75 * 60 = 45 pieces of bread. Wanda and Jane brought a total of 30 treats + 60 treats + 45 pieces of bread + 90 pieces of bread = 225.. The answer is: 225.

Let's think step by step. He has 10 pairs of shoes and each pair is made of 2 individual shoes for a total of 10 * 2 = 20 shoes. He has already polished 45% of the 20 individual shoes so he has polished .45 * 20 = 9 shoes. He has 20 shoes and has already polished 9 shoes so he has 20 - 9 = 11 more shoes to polish.. The answer is: 11.
