## Elementary Algebra

The solution set is {t|t $\lt$ 100} , or (-$\infty$, 100) in interval notation.
Use the properties of inequalities to solve this inequality. 0.08t + 0.1(300 - t) $\gt$ 28 Multiply both sides by 100 to clear the equation of all decimals. 8t + 10(300 - t) $\gt$ 2800 Use the distributive property. 8t + 3000 - 10t $\gt$ 2800 3000 - 2800 $\gt$ 10t - 8t 200 $\gt$ 2t Divide both sides by 2. 100 $\gt$ t The solution set is {t|t $\lt$ 100} , or (-$\infty$, 100) in interval notation.
