Question 458743: please help me write an equation that represents the total cost c of an item costing x dollars. a salesperson needs to calculate the cost of an item with a sale tax of 8.25%. Answer by algebrahouse.com(1659) (Show Source):
You can put this solution on YOUR website! total cost = c
cost of item = x
tax = 8.25% = .0825 {change percent to decimal by moving decimal point left two}
To find tax:
- multiply cost of item by percent tax (as a decimal)
= .0825x
To find total cost:
- add cost of item plus tax
= x + .0825x
