Question

You are buying potato chips at the grocery store. You have a manufacturer's coupon for $1.00 off and the store is offering 20% off if you buy 2 bags. How do you compute your final cost? is the answer Subtract, multiply, add, or subtract $1.00 from the first bag?

GPT-5 mini · Answer

Do the percent-off first (multiply), then take off the $1 coupon (subtract).

If each bag costs P, 20% off makes each cost 0.8P. Two bags cost 2·0.8P = 1.6P. Then subtract the $1 manufacturer coupon (usually applied to one bag), so final cost = 1.6P − 1.

(Example: P = $2.50 → each is $2.00 after 20% off, two = $4.00, minus $1 coupon = $3.00 total.)
