Amy has set aside $150 a month for her cell phone bill. Thecost for a monthly cell phone plan is a $65 access fee plus $20 per gigabyte of data used. Which expression represents the amount of money Amy has left from her monthly budget after she pays her cell phone bill?
150-(65+20g)
To find the amount of money Amy has left from her monthly budget after she pays her cell phone bill, we need to subtract the cost of the cell phone bill from her monthly budget.
Amy's monthly budget is $150.
The cost for a monthly cell phone plan is a $65 access fee plus $20 per gigabyte of data used.
Let's assume Amy uses "x" gigabytes of data.
The cost of the cell phone bill, therefore, would be $65 (access fee) plus $20 multiplied by "x" (cost per gigabyte of data).
So, the expression for the cost of the cell phone bill would be 65 + 20x.
To find the amount of money Amy has left from her monthly budget, we need to subtract the cost of the cell phone bill from her monthly budget:
Amount of money Amy has left = Amy's monthly budget - Cost of the cell phone bill
Amount of money Amy has left = $150 - (65 + 20x)
So, the expression that represents the amount of money Amy has left from her monthly budget after she pays her cell phone bill is $150 - (65 + 20x).
