Answer:

Andy added 70 to 5 instead of multiplying 70 by 5.

Step-by-step explanation:

We have been given that Mrs.Ruiz bought 5 bags of balloons for a party. Each bag contained 70 balloons. Andy said Mrs.Ruiz bough a total of 75. Andy is incorrect what error did Andy make when calculating the total number of balloons.

To find the total number of balloons in 5 bags, we will multiply number of balloons in each bag by 5.

\text{Total balloons}=5\times 70

\text{Total balloons}=350

Therefore, the total number of balloons in 5 bags would be 350 balloons.

Andy added 70 to 5 instead of multiplying 70 by 5.

70+5=75

The average rate of change of credit card is $ 401.79 /year.

<h3>What is Average Rate?</h3>
  • A single rate that is a weighted average of the different rates that are applicable to property in various locations.
  • An average is a single number calculated as the average of a set of numbers, typically calculated as the sum of the numbers divided by the total number of numbers in the set (the arithmetic mean).

<u>Solution</u>

The difference of credit card debt between the year 2006 and 1992 = 8900 - 3275 = $5625

The difference of years between the year 2006 and 1992 = 2006 - 1992 = 14

average rate of change of credit card debt with respect to time = \frac{difference of credit card debt}{difference of years}

average rate = \frac{5625}{14} = $ 401.79 / year
