To break down the calculation of the total amount on the invoice, let's calculate each component step by step:
1) For the supplies:
- 4 bottles of alcohol at $2.25 each: 4 * $2.25 = $9.00
- 3 thermometers at $1.95 each: 3 * $1.95 = $5.85
- 6 boxes of cotton at $0.29 each: 6 * $0.29 = $1.74
- 6 bottles of mouthwash at $0.89 each: 6 * $0.89 = $5.34
- 11 cartons of cotton swabs at $0.39 each: 11 * $0.39 = $4.29
- 3 hypo needles at $0.39 each: 3 * $0.39 = $1.17
Total supplies amount = $9.00 + $5.85 + $1.74 + $5.34 + $4.29 + $1.17 = $27.39
2) Discount:
The doctor receives a 3% discount on the total supplies amount of $27.39.
Discount amount = 3% of $27.39 = 0.03 * $27.39 = $0.82
Adjusted supplies amount after discount = $27.39 - $0.82 = $26.57
3) Sales tax:
Sales tax is calculated as 6% of the adjusted supplies amount:
Sales tax amount = 6% of $26.57 = 0.06 * $26.57 = $1.59
4) Total on the invoice:
Total on invoice = Adjusted supplies amount + Sales tax amount
Total on invoice = $26.57 + $1.59 = $28.16
Therefore, the total amount on the invoice is $28.16.
