a = amount invested at 13%
b = amount invested at 2%
we know the total amount invested is 8200, so if the first amount is say "a", the second amount must be the slack left from subtracting "a", namely b = 8200 - a.
we also know 13% of "a" plus 2% of "b" yielded an interest of $461 in a year.
Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
<u>Given the following data;</u>
Experimental value = 4.5cm
Theoretical value = 4.8cm
<em>Substituting into the equation, we have;</em>
Percent error = 6.25%
