Randy went to the store and brought a shirt that cost $42.00 before taxes and discount. The shirt was on sale for a discount of 20% before tax. The sales taxes was 3%. What did randy pay for the shirt after discount and tax

Step-by-step explanation:

The 20% discount amounted to ...

  0.20 × $42.00 = $8.40

so the price before tax was ...

  $42.00 -8.40 = $33.60

The tax amount is 3% of this value, so is ...

  0.03 × $33.60 = $1.008 ≈ $1.01

So the total price paid for the shirt was ...

  $33.60 +1.01 = $34.61

Randy paid $34.61 for the shirt after discount and tax.

___

Alternate solution

You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...

  $42.00×0.80×1.03 = $34.608 ≈ $34.61

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
