A student missed 5 problems on a biology 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" be the number of problems on the test.
----------
44% of x were correct
-----
56% of x were incorrect
----
Equation
0.56x = 5
x = 5/0.56
---
x = 8.9286
---
Round up to x = 9
