The error of percentage is the amount of error over the original amount.

22/95 = .2315 or 23.2% to the nearest tenth of a percent

Solution: x>106
The company must sell at least 106 items to make a profit.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Revenue: 7.5x – 100
Costs: 79.86 + 5.8x
To make a profit, a company’s revenue must be greater than its operating costs.
So:
7.5x – 100 > 79.86 + 5.8x
Solving for x (number of items sold)
7.5x-5.8x>79.86+100
1.7x >179.86
x>179.86/1.7
x> 105.8
x>106
The company must sell at least 106 items to make a profit.
