Question

ind the unit price in cents per diaper for each of the brands shown below. Round to the nearest tenth of a cent.Brand A:  Diapers, :  ¢ per diaper   Brand B:  Diapers, :  ¢ per diaper   Note: Rounding to the nearest tenth of a cent is the same as rounding to the nearest thousandth of a dollar.

Answer 1

You are calculating a rate here. (Look out for the word "per").

If the units are ¢ per diaper, you need to divide the total number of cents by the total number of diapers.

(Don't forget to convert from dollars into cents).

Brand A: 699 cents ÷ 20 diapers = 34.95 cents per diaper (this rounds to 35.0 cents per diaper)

Brand B: 1,199 cents ÷ 45 diapers = 26.64444 cents per diaper (this rounds to 26.6 cents per diaper)
