Final answer:
After accounting for Sally's monthly expenses and savings, she has $30 left, which means she can save enough for the $75 pair of pants after one month by saving this remaining balance.
Step-by-step explanation:
To calculate how much Sally can save towards purchasing the $75.00 pair of pants at Urban Outfitters, we must start by evaluating her monthly expenses and income. Sally's monthly income is $200. From this, she pays $50.00 for her phone bill, $50.00 for groceries, and $40.00 for gas. She also puts away $30.00 in savings. After covering all her expenses and savings, the rest can be used for discretionary spending or additional savings.
Now, let's calculate her remaining balance after her expenses and savings:
Monthly Income: $200
Phone Bill: -$50
Groceries: -$50
Gas: -$40
Savings: -$30
Remaining Balance = Income - (Phone Bill + Groceries + Gas + Savings)
Remaining Balance = $200 - ($50 + $50 + $40 + $30)
Remaining Balance = $200 - $170
Remaining Balance = $30
Sally has $30 left to spend or save additionally. Therefore, if she chooses to save the entire remaining balance, she can afford the pair of pants after one month.
