Answer 2

Answer: 1. 0.19125 dollars per ounce, 2. 0.16083 dollars per ounce.

Explanation:

In first question, a 24 ounce box of cornflakes cost $4.59

Therefore, 24 ounce = 4.59 dollars

⇒ 1 ounch =
`(4.59)/(24)` dollars

⇒ 1 ounch = 0.19125 dollars

⇒ Price of 1 ounce box of cornflakes equals to 0.19125 dollars.

⇒Thus the unit rate price of cornflakes = 0.19125 dollars per ounce

In first question, a 24 ounce box of cornflakes cost $4.59

Therefore, 36 ounce = 5.79 dollars

⇒ 1 ounch =
`(5.79)/(36)` dollars

⇒ 1 ounch = 0.16083 dollars

⇒ Price of 1 ounce box of cornflakes equals to 0.16083 dollars.

⇒Thus the unit rate price of cornflakes = 0.16083 dollars per ounce
