Answer : C
Explanation
Step 1:
Discount of trader A = 40% of $360 = 0.4 × 360 = $144
Sale price of trader A = $360 − $144 = $216
Step 2:
Discount of trader B = 30% of $300 = 0.3 × 300 = $90
Sale price of trader B = $300 − $90 = $210
Step 3:
Since 210 < 216, purchasing from Trader B is a better buy.
Answer : A
Explanation
Step 1:
Discount of trader A = 25% of $510 = 0.25 × 510 = $127.50
Sale price of trader A = $510 − $127.50 = $382.50
Step 2:
Discount of trader B = 30% of $540 = 0.3 × 540 = $162
Sale price of trader B = $540 − $162 = $378
Step 3:
Since 378 < 382.50, purchasing from Trader B is a better buy.
Answer : B
Explanation
Step 1:
Discount of trader A = 25% of $420 = 0.25 × 420 = $105
Sale price of trader A = $420 − $105 = $315
Step 2:
Discount of trader B = 30% of $460 = 0.3 × 460 = $138
Sale price of trader B = $460 − $138 = $322
Step 3:
Since 315 < 322, purchasing from Trader A is a better buy.
Answer : D
Explanation
Step 1:
Discount of trader A = 25% of $360 = 0.25 × 360 = $90
Sale price of trader A = $360 − $90 = $270
Step 2:
Discount of trader B = 30% of $380 = 0.3 × 380 = $114
Sale price of trader B = $380 − $114 = $266
Step 3:
Since 266 < 270, purchasing from Trader B is a better buy.
Answer : B
Explanation
Step 1:
Discount of trader A = 25% of $320 = 0.25 × 320 = $80
Sale price of trader A = $320 − $80 = $240
Step 2:
Discount of trader B = 30% of $350 = 0.3 × 350 = $105
Sale price of trader B = $350 − $105 = $245
Step 3:
Since 240 < 245, purchasing from Trader A is a better buy.
Answer : D
Explanation
Step 1:
Discount of trader A = 25% of $400 = 0.25 × 400 = $100
Sale price of trader A = $400 − $100 = $300
Step 2:
Discount of trader B = 30% of $420 = 0.3 × 420 = $126
Sale price of trader B = $420 − $126 = $294
Step 3:
Since 294 < 300, purchasing from Trader B is a better buy.
Answer : A
Explanation
Step 1:
Discount of trader A = 20% of $110 = 0.2 × 110 = $22
Sale price of trader A = $110 − $22 = $88
Step 2:
Discount of trader B = 30% of $130 = 0.3 × 130 = $39
Sale price of trader B = $130 − $39 = $91
Step 3:
Since 88 < 91, purchasing from Trader A is a better buy.
Answer : C
Explanation
Step 1:
Discount of trader A = 30% of $200 = 0.3 × 200 = $60
Sale price of trader A = $200 − $60 = $140
Step 2:
Discount of trader B = 35% of $220 = 0.35 × 220 = $77
Sale price of trader B = $220 − $77 = $143
Step 3:
Since 140 < 143, purchasing from Trader A is a better buy.
Answer : B
Explanation
Step 1:
Discount of trader A = 20% of $200 = 0.2 × 200 = $40
Sale price of trader A = $200 − $40 = $160
Step 2:
Discount of trader B = 15% of $180 = 0.15 × 180 = $27
Sale price of trader B = $180 − $27 = $153
Step 3:
Since 153 < 160, purchasing from Trader B is a better buy.

Step 2:
Discount of trader B = 30% of $270 = 0.3 × 270 = $81
Sale price of trader B = $270 − $81 = $189
