John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total?
Let's think: He got a discount of 400 * .8 = $320. He got that discount for 3 - 1 = 2 visits. So each of those visits cost 400 - 320 = $80. So he paid 2 * 80 = $160 for those visits. That means he paid a total of 400 + 160 + 100 = $660.. The answer is: 660.

A store ordered 300 more than twice as many pens as it did pencils at $5 each. If the cost of a pencil was $4, and the store ordered 15 boxes, each having 80 pencils, calculate the total amount of money they paid for the stationery.
Let's think: If the store ordered 15 boxes, each having 80 pencils, they ordered 15 * 80 = 1200 pencils. If the cost of a pencil was $4, the store paid $4 * 1200 = $4800 for all the pencils. Twice as many pens as pencils that the store ordered are 2 * 1200 = 2400. If A store ordered 300 more than twice as many pens as it did pencils, it ordered 2400 + 300 = 2700 pencils. Since the cost of the pens was $5, the store paid 2700 * $5 = $13500 for the pens. The total amount of money they paid for the stationery is 13500 + 4800 = $18300.. The answer is: 18300.

Tommy ordered a total weight of 10 kilograms of apple, orange, grape, and strawberry fruits. He ordered 3 kilograms of apples, 1 kilogram of orange, and 3 kilograms of grapes. How many kilograms of strawberries did he order?
Let's think: Tommy ordered 3 + 3 + 1 = 7 kilograms of apples, oranges and grapes altogether. Therefore, Tommy ordered 10 - 7 = 3 kilograms of strawberries.. The answer is: 3.

Madeline needs to buy 2 * 20 = 40 seeds to make sure that she will have 20 flowers. Thus, Madeline will need to buy 2 packs of flowers to have at least 40 seeds. Thus, Madeline will spend 2 * 5 = $10 on seeds.. The answer is: 10.
