Questions & Step-by-Step Solutions

A family spends an average of $200 per week. If they increase their spending by 10%, what will be their new average spending?
  • Step 1: Identify the current average spending, which is $200.
  • Step 2: Calculate 10% of the current average spending. To do this, multiply $200 by 0.10 (which is the decimal form of 10%).
  • Step 3: 10% of $200 is $20 (because 200 * 0.10 = 20).
  • Step 4: Add the $20 (which is 10% of $200) to the original average spending of $200.
  • Step 5: The new average spending is $220 (because 200 + 20 = 220).
  • Percentage Increase – Understanding how to calculate a percentage increase on a given amount.
  • Basic Arithmetic – Performing addition and multiplication to find the new average spending.
