Let's find out how the marked price ($MP$) is split between cash and credit card purchases.For the cash payment part:The discount offered is $10\%$.Therefore, Cash Paid = $90\%$ of $M{P}_{\text{cash}}$ $
\ 228,000 = 0.90 \times MP_{\text{cash}}
$$
$$M{P}_{\text{cash}}=\frac{228,000}{0.90}=\$253,333.33$$
This interpretation implies a non-integer marked price division, so let's re-verify the standard wording of this question type where the values are clean fractions of the total.Let the remaining total marked price paid by credit card be:
$$M{P}_{\text{card}}=\text{Total }MP-M{P}_{\text{cash}}$$
Instead, let's observe the options provided to find the exact intended interpretation:Total Marked Price = \ 400,000$.Ifthequestionintendsthatshepaid$ \$228,000$ in cash, the corresponding marked price covered by cash is \ 228,000 / 0.90 = \$253,333.33$.Remaining marked price for credit card = \ 400,000 - \253,333.33 = \ 146,666.67$.Discountoncreditcardamount=$ 5\%$,sodiscountedprice=$ 0.95 \times \146,666.67 = \ 139,333.33$.With$ 2\%$surcharge:$ \139,333.33 \times 1.02 = \ 142,120$,whichdoesnotmatchtheoptionsexactly.Le{t}^{\prime }scheckalternativedatafit:Iftheremainingmarkedpriceisexactly$ \$150,000$:Credit card discounted amount = \ 150,000 \times 0.95 = \$142,500$.Including $2\%$ surcharge = \ 142,500 \times 1.02 = \$145,350$.Let's test Option B: \ 158,100$.Iffinalcardpayment=$ \$158,100$, then before $2\%$ surcharge, the amount is:
$$\frac{158,100}{1.02}=\$155,000$$
The marked price corresponding to this before a $5\%$ discount would be:
$$\frac{155,000}{0.95}=\$163,157.89$$
