The statement that the average weekly allowance A varies directly as the grade G means that there is a constant number k, a number that doesn't change with grade level, so that A = k × G. Since grade 8 students (G = 8) have an average weekly allowance of $8.56 (A = $8.56) you know that
and hence
Thus A = $1.07 × G. If G = 5 what is A? The time T required to do a job varies inversely as the number of people P working means that there is a constant number k so that T = k × 1/P. As I did in the previous problem use the known values to determine k and then apply this value to answer the question. Penny
