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.
[tex]\text{Total balloons}=5\times 70[/tex]
[tex]\text{Total balloons}=350[/tex]
Therefore, the total number of balloons in 5 bags would be 350 balloons.
Andy added 70 to 5 instead of multiplying 70 by 5.
[tex]70+5=75[/tex]
