Question

Which is a better deal on a $50 item: 45% off original price or 30% off, plus an additional 20% off at the register? Your answer must include your math calculations

Answer 1

First Deal at 45%→ $50 - 50(45%) = 50 - 22.5 = $27.5 (net to pay)

Second Deal: a) 30% off → $50 - 50(30%) = 50 - 15 = $35
b) Additional 20% (on the remaining from a)) →
$35 - 35(20%) = 35 - 7 = $28 (net to pay)

Then the 1st deal at 45% is better
