The trap in this question: \(B\) napkins =
Work Work needs to be
divided by rate in order to get
timeHow many seconds to fold \(B\) napkins?
Rate: \(\frac{H.napkins}{53secs}=\frac{H}{53}\)
Work: \(B\) napkins
\(r*t=W\)
\(\frac{H}{53}*t=B\)
Time, \(t=\frac{B}{(\frac{H}{53})}=(B*\frac{53}{H})=\frac{53B}{H}\)
Answer A
