Answer:
Richard’s account balance at the end of the week = US$ 132.45
Explanation:
1. Let's review the information provided to us to answer the question correctly:
Richard’s checking account balance at the beginning of the week = $57.34
2. What was Richard’s account balance at the end of the week?
Deposits of the week = US$ 163.75
Expenses of the week = Groceries + Credit card bill + Gas
Expenses of the week = 25.37 + 50 + 13.27
Expenses of the week = US$ 88.64
Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week
Replacing with the real values:
Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64
Richard’s account balance at the end of the week = US$ 132.45
