Add the two bags together, multiply by .80, and then subtract $1.00.
Add the two bags together, multiply by .80, and then subtract $1.00.

Subtract $1.00 from the first bag, add them together, and then multiply by .80.

Answer 1

Add the two bags, multiply by 0.80, then subtract $1.00.

If each bag costs p, total = 2p, after 20% off = 0.8(2p) = 1.6p, then subtract the $1 coupon → 1.6p − 1.
