a banks monthly charge for a checking account is $5 plus $0.03 per check. if the total monthly charge for one account is $6.44, how many checks were written? number of checks:
Answer
Explanation:
Step1: Set up an equation
Let $x$ be the number of checks. The total monthly charge equation is $5 + 0.03x=6.44$.
Step2: Isolate the term with $x$
Subtract 5 from both sides: $0.03x=6.44 - 5$. So, $0.03x = 1.44$.
Step3: Solve for $x$
Divide both sides by 0.03: $x=\frac{1.44}{0.03}=48$.
Answer:
48
