Given the inequality:

200 + 0.75x ≤100 + 2.50x

Solution:

In order to solve the inequality, we transpose 0.75x and 100 on the opposite sides of the equation, hence we must take note that when transposing a number, the sign changes.

200 + 0.75x ≤100 + 2.50x

200 - 100  ≤  2.50x - 0.75x

100  ≤ 1.75x

Divide both sides by 1.75 in order to get the value of x.

57.14 ≤ x

Final answer:

57.14 ≤ x
