Leya [2.2K]

Answer:

The correct answer option is b. Darius will get the better deal buying one 16 ounce bottle.

Step-by-step explanation:

We know that a 16 ounce bottle of the salad dressing is for $3.36 while a 10 ounce bottle is priced at $2.30.

Darius has a coupon for 40 cents off if he buys two 10 ounce bottles. We are to determine what is the better buy.

Price of one 16 ounce bottle = $3.36

Price of two 10 ounce bottles = (2.30 × 2) - 0.4 = $4.2

Therefore, Darius will get the better deal buying one 16 ounce bottle.
