Please help with the following question.
If the following equation, y is the weight in pounds that a person can bench-press and x is the amount of lifting done per week on their newly begun exercise program:
y = 100+1.2x
How much lifting exercise must this person do to be able to bench-press 130 pounds?
y = 100 + 1.2x
130 = 100 + 1.2x
Solve for x
30 = 1.2x
x = 30/1.2 = ?
