Question 192549
    "A student missed 9 problems on a chemistry test and received a grade of 44%. If all the problems were of equal value, how many problems were on the test? Round off your answer to the nearest integer."
.
Let x = number of problems on the test
then
(x-9)/x = .44
x-9 = .44x
.56x = 9
x = 9/.56
x = 16.071
or, rounded to the nearest integer:
x = 16 problems on the test
