He must have 88% of the 1400 points possible by the end of the term to receive credit for the class.
What is the minimum number of additional points he must earn by the end of the term to receive credit for the class??
:
Let x = no. of additional points required to accomplish this
:
x + 1121 => .88(1400)
:
x + 1121 => 1232
:
x => 1232 - 1121
;
x => 111 points minimum
:
Check
111 + 1121 = .88(1400)
1232 = 1232
:
He must make at least 111 more points to get a grade of at least 88%
