IQ = (Mental Age / Chronological Age) x 100
According to the information, Jeremy is 8 years old (chronological age) but performs as well as most 10-year-olds (mental age). Plugging these values into the formula gives us:
IQ = (10 / 8) x 100
IQ = 1.25 x 100
IQ = 125
Therefore, the answer is d) 125. Jeremy's IQ would be 125 if she is performing at the level of an average 10-year-old at the age of 8.
