samir, a carpenter, spent $300 on specialty tools to make toy horses for children. for each horse he makes, he spends $75 on supplies. he charges $125 for each horse. how many horses must samir sell in order to break even?\n2\n3\n4\n6
Answer
Answer:
D. 6
Explanation:
Step1: Set up cost - revenue equations
Let $x$ be the number of horses. Cost $C = 300+75x$, Revenue $R = 125x$.
Step2: Set cost equal to revenue for break - even
$300 + 75x=125x$.
Step3: Solve for $x$
Subtract $75x$ from both sides: $300=125x - 75x$, so $300 = 50x$. Then divide both sides by 50: $x=\frac{300}{50}=6$.
