We have to solve the inequality for h (height)
260 ≤ 4h + 28 < 324
first, subtract 28 to all sides of the inequality:
260-28 ≤ 4h + 28 -28 < 324-28
232 ≤ 4h < 296
Then divide all sides by 4:
232/4 ≤ 4h /4 < 296/4
58≤ h < 74
So, the range of heights of the cheerleaders in inches is:
58 ≤ h < 74
To convert it into feet we have to divide by 12:
58/12= 4.83 feet = 4 feet and 10 inches
74/12= 6.16 feet = 6 feet and 2 inches
So:
4 feet and 10 inches ≤ h < 6 feet and 2 inches
The possible heights are:
5 feet. 11 inches
5 feet, 8 inches
5 feet, 4 inches
5 feet 3 inches
4 feet, 10 inches
