Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let t represent the number of t-shirts she needs to sell in order to make a profit. Since:
t > 100 and the price is $15 per shirt, hence:
Money spent = $15 * 100 = $1500
Money lost in sell 90 shirts = (100 - 90) * 15 = $150
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.
