Number of rotations r < 5.25

Step-by-step explanation:

Given: bottom of the desktop is 74.5 cm from the floor.

Top of Ignacio's legs are 49.3 cm from the floor.

Each clockwise rotation on the knob raises Ignacio's legs by 4.8 cm.

To find: Inequality to determine the number of clockwise rotations r, Ignacio could make with the knob without his legs touching the desk.

Solution: Distance between Ignacio's legs and the base of the desktop = 74.5 -49.3 = 25.2

Therefore inequality will be

Height raised in one rotation × r < 25.2

4.8×r < 25.2

r < 25.2÷4.8

r  < 5.25
