a vending machine sells chips for $0.50 and candy bars for $1.00. if jim spent $5.50 on snacks in the machine over the course of a week, how many candy bars did he buy?\na 1\nb 2\nc 3\nd cannot be determined from the given information

Answer

Explanation:

Step1: Set up an equation

Let $x$ be the number of chips and $y$ be the number of candy - bars. The total amount spent equation is $0.5x + 1y=5.5$, or $y = 5.5−0.5x$.

Step2: Analyze the unknowns

We have one equation with two unknowns ($x$ and $y$). There are multiple non - negative integer solutions for $x$ and $y$ (e.g., if $x = 1$, then $y=5$; if $x = 3$, then $y = 4$ etc.).
