What is the process for calculating change given a purchase amount and payment?

Back

To calculate change, subtract the purchase amount from the payment amount. For example, if a customer pays $20 for a $3.84 item, the change is $20 - $3.84 = $16.16.

How do you calculate the total amount of food needed for multiple days?

Back

To calculate the total amount of food needed, multiply the number of days by the daily consumption. For example, if each kitten eats 2 cans per day for 3 kittens over 7 days, the total is 3 kittens * 2 cans/day * 7 days = 42 cans.

What is the formula for calculating the average of a set of numbers?

Back

The average (mean) is calculated by adding all the numbers together and then dividing by the count of the numbers. For example, for sales calls: (8 + 7 + 9 + 5 + 7) / 5 = 7.2.

Front

How do you calculate a percentage of a total?

Back

To calculate a percentage of a total, multiply the total by the percentage (in decimal form). For example, to find 75% of 6000, calculate 6000 * 0.75 = 4500.

Front

What is the significance of understanding volume in real-world applications?

Back

Understanding volume is crucial in various fields such as engineering, construction, and agriculture, as it helps in determining capacities and quantities needed for projects.
