You have a coupon for $6 off the price of any large pizza. You also get a 20% discount if you show your student id. How much more would you pay for a large pizza if the cashier applies the coupon first?

Say a pizza is normally $10 $6 off first: now its $4 20% discount: 4 - 0.2*4 = 3.20 ---- 20% off first: 10-0.2*10 = $8 $6 off: $2 --- 3.2 - 2 = (1.20)
