If you would like to find the inequality to solve to find the amount that each member should raise to meet the goal, you can do this using the following steps:
x ... the amount of money that each member should raise
x * 23 members + $750 >= $1,800
x * 23 + 750 >= 1,800
x * 23 >= 1,800 - 750
x * 23 >= 1,050 /23
x >= 1,050 / 23
x >= $45.65
The correct result would be: x * 23 members + $750 >= $1,800.
