Fabian is shopping at a nearby supermarket. He wants to buy 5 kilograms of apples, 3 packs of sugar, and 500 grams of walnuts. One kilogram of apples costs $2, and one kilogram of walnuts costs $6. One pack of sugar is $1 cheaper than one kilogram of apples. How much Fabian needs to pay for the items he wants to buy?
Let's think: The apples cost Fabian 5 kg * $2 / kg = $10. For the walnuts Fabian needs to pay 0.5 kg * $6 = $3. One pack of sugar costs $2 - $1 = $1. So Fabian will pay $1 / pack * 3 = $3 for sugar. In total, Fabian needs to pay $10 + $3 + $3 = $16.. The answer is: 16.

Edith has 80 novels stuffed on her schoolbook shelf, half as many as the number of writing books she has stuffed in her suitcase. How many novels and writing books does Edith have altogether?
Let's think: Edith's number of writing books is 80 * 2 = 160, twice the number of novel books she has. Altogether, Edith has 160 + 80 = 240 books.. The answer is: 240.

Marissa's sunflower is 21 inches taller than her little sister. If her sister is 4 feet 3 inches tall, how tall is Marissa's sunflower in feet?
Let's think: Since 1 foot is equal to 12 inches, then 4 feet is equal to 4 x 12 = 48 inches. So, Marissa's sister is 48 + 3 = 51 inches tall. The sunflower is 51 + 21 = 72 inches tall. Therefore, the sunflower is 72 / 12 = 6 feet tall.. The answer is: 6.

A curry house sells curries that have varying levels of spice. Recently, a lot of the customers have been ordering very mild curries and the chefs have been having to throw away some wasted ingredients. To reduce cost and food wastage, the curry house starts monitoring how many ingredients are actually being used and changes their spending accordingly. The curry house needs 3 peppers for very spicy curries, 2 peppers for spicy curries, and only 1 pepper for mild curries. After adjusting their purchasing, the curry house now buys the exact amount of peppers they need. Previously, the curry house was buying enough peppers for 30 very spicy curries, 30 spicy curries, and 10 mild curries. They now buy enough peppers for 15 spicy curries and 90 mild curries. They no longer sell very spicy curries. How many fewer peppers does the curry house now buy?
Let's think:
The curry house previously bought 3 peppers per very spicy curry * 30 very spicy curries = 90 peppers for very spicy curries. They also bought 2 peppers per spicy curry * 30 spicy curries = 60 peppers for spicy curries. They also bought 1 pepper per mild curry * 10 mild curries = 10 peppers for mild curries. So they were previously buying 90 + 60 + 10 = 160 peppers. They now buy 2 peppers per spicy curry * 15 spicy curries = 30 peppers for spicy curries. They also now buy 1 pepper per mild curry * 90 mild curries = 90 peppers for mild curries. So they now buy 30 + 90 = 120 peppers. This is a difference of 160 peppers bought originally - 120 peppers bought now = 40 peppers.. The answer is: 40.
