Answer: B) \(=10\frac{d}{t}\)
Step-by-step explanation:
Given: The number of questions Jennifer can answer on a worksheet is directly proportional to how many minutes she studied.
If she studies t minutes (independent variable) she can answer d questions (dependent variable) then
\(d=kt\), where k= proportionality constant
Then, \(k=\frac{d}{t}\)
If she studied 10 minutes, the number of question she answered=\(10k\)
If we put value of k in it, we get \(=10\frac{d}{t}\)
