Conditions She makes 22 dollars per hour. Her entire wage = 22*H where x is the number of hours. 5% of that goes to a charity. When she's taken out the donation, she needs to have at least 748 left
Equation 22*H - 5%(22*H) > 748
Simplification Take out 22H from both sides of the minus sign 22H ( 1 - 5%) > 748 Change the 5% to a fraction. 22H (1 - 5/100) > 748 22H (1 - 0.5)> 748 22H (0.95) > 748
Solve what is left. Multiply 22H by 0.95 22H*0.95 > 748 20.9*H > 748 Divide by 20.9 H > 748 / 20.9 H > 35.7 which should be rounded to 36
Answer H>35.7 H>36 hours (<em>rounded)</em> C <<<<< Answer
For anything to do with force you have to assume an even amount of force is spread out evenly. But for things like growing rate you have all those variables so you can't assume a constant growing rate like acceleration.
