Aliya and her classmates are sent by their teacher to the field to collect insects for science class study. The Boys collected 200 insects and the girls collected 300 insects. The teacher decided to divide the class equally into four groups that each get an equal number of insects so that each group could study together. What was the number of insects given to each group?
Let's think: The total number of insects collected is 200 insects + 300 insects = 500 insects. When the teacher divided the class into four groups, each group got 500 insects / 4 groups = 125 insects / group.. The answer is: 125.

There are 10 cars parked in a mall’s parking lot, each with the same number of customers inside. Each customer only makes 1 purchase. If the sports store makes 20 sales and the music store makes 30 sales, how many customers are in each of the cars?
Let's think: As each sale represents a customer, there must be a total of 20 sports store sales + 30 music store sales = 50 customers. There is an equal number of customers in every car, so there must be 50 total customers / 10 cars = 5 customers in each car.. The answer is: 5.

Victoria had $500. She went to the market and bought 2 packets of rice each at $20, 3 packets of wheat flour each at $25, and 1 soda at $150. What was her remaining balance?
Let's think: In total, she spent 2 * $20 + 3 * $25 + $150 = $265. Thus her remaining balance is $500 - $265 = $235.. The answer is: 235.

Ryan builds model mustang cars. A full size mustang is 240 inches long. The mid-size model that Ryan creates is 1/10th the size, and the smallest model that Ryan creates is half the size of the mid-size model. How many inches long is the smallest model mustang?
Let's think:
Mid - size:240 / 10 = 24 inches. Small Model:24 / 2 = 12 inches.. The answer is: 12.
