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.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
