Answer:
Less than the actual amount because he rounded to the nearest $100.
Explanation:
We are given that Thomas' credit card bills for January through April were $103.49, $215.62, $346.79, and $122.76.
He estimated that his credit charges totaled $700 over these 4 months.
Firstly, January's credit card bill is $103.49;
When we round this to the nearest $100, it will be $100 because this number lies between $100 and $200 and is close to $100 as compared to $200.
So, January's credit card bill rounded to the nearest $100 will be $100.
Similarly, February's credit card bill is $215.62;
When we round this to the nearest $100, it will be $200 because this number lies between $200 and $300 and is close to $200 as compared to $300.
So, February's credit card bill rounded to the nearest $100 will be $200.
Now, March's credit card bill is $346.79;
When we round this to the nearest $100, it will be $300 because this number lies between $300 and $400 and is close to $300 as compared to $400.
So, March's credit card bill rounded to the nearest $100 will be $300.
Lastly, April's credit card bill is $122.76;
When we round this to the nearest $100, it will be $100 because this number lies between $100 and $200 and is close to $100 as compared to $200.
So, April's credit card bill rounded to the nearest $100 will be $100.
Now, the actual amount of bill for four months is = $103.49 + $215.62 + $346.79 + $122.76 = $788.66
And the total amount of bill when rounded to nearest $100 = $100 + $200 + $300 + $100 = $700
This means that the estimate of Thomas is Less than the actual amount because he rounded to the nearest $100.
