Find the sales tax and the total bill on an order of office supplies costing $72.34 if the tax rate is 7%

tax: 0.07 * 72.34 = ___

total: add the tax to 72.34

To find the sales tax and total bill, you'll need to calculate the tax amount first and then add it to the initial cost.

Step 1: Calculate the tax amount:
Tax amount = Cost of office supplies * Tax rate
Tax amount = $72.34 * 7%
Tax amount = $72.34 * 0.07
Tax amount = $5.06

Step 2: Calculate the total bill:
Total bill = Cost of office supplies + Tax amount
Total bill = $72.34 + $5.06
Total bill = $77.40

Therefore, the sales tax on the order is $5.06 and the total bill is $77.40.

To find the sales tax, you need to multiply the cost of the office supplies by the tax rate. Here's how you can do it step by step:

Step 1: Calculate the sales tax.
- Convert the tax rate from a percentage to a decimal by dividing it by 100.
Tax rate = 7% ÷ 100 = 0.07
- Multiply the cost of the office supplies by the tax rate.
Sales tax = $72.34 × 0.07 = $5.06

Step 2: Calculate the total bill.
- Add the cost of the office supplies to the sales tax.
Total bill = $72.34 + $5.06 = $77.40

Therefore, the sales tax on the order of office supplies is $5.06, and the total bill, including tax, is $77.40.
