Hi. Please tell me where did I go wrong

Normal situation: $4/chip + $50 FOR 11 days
Urgent situation: $4+$2 (additional surcharge for each day <11 days)/day + $100 ($ 50 under regular condition + $50 as additional payment)

According to question -
Normal situation: $200 ($4x50 chips) + $50 = $250

Since it requires 2 days before standard 11 days, hence
For 1 day before standard 11 days charge - $4 + $2 = $6
For 2 days before standard 11 days charge - $4 + $4 = $8

Urgent situation: $8x50 + $100 = $500

Urgent request greater than regular order by = ($500-$250)/ $ 250x 100 = 100%

The price without the rush would have been $50payment + 50chips*$4/chip = $250.
The rush is nine days early, so we need to add $18 to the price of each chip plus an additional $50 payment. We now have $100 payments + 50chips*$22/chip = $1200.
We are asked what percent greater than the normal price is the rushed price. Percent change is difference/original. Difference is $950. Original is $250. Answer is 950/250, or 19/5. that's 380% (if you get woozy with this last bit, notice that 19/5 is just a little less than 4, so only one answer choice is close).

Answer choice C.

Dear all, please note that the whole trick is in paraphrasing of the question "A dealership orders 50 chips 2 days prior to his desired pickup date" in other words, he needs to pick his order in 2 days only so the extra fees will be calculated based on 11-2= 9 days.

9 days x 2$ per chip per day = $18 extra fees in addition to 4 regular fees = $22 per chip + $50 one-time charges + $50 extra charges so total of
Urgent order = 50 chips x $22 = $1100 + $100 ($50 + $50) = 1200
Regular order = 50 chips x $4 + $50 one-time payment = $250


Then finally, to calculate how much the urgent order is higher than the regular one (1200-250)/250 *100 = 380.
