Answer:

The cost of an ounce of raisin is;


0.80\text{ dollars}

The number of ounces we can get with 1 dollar is;


1.25\text{ ounces}

Step-by-step explanation:

Given that Jackson bought 5 ounces of raisins for 4 dollars.

The cost of one ounce of raisin can be calculated by dividing the cost of five ounces divided by the number of ounces;


\begin{gathered} 5\text{ ounces }\rightarrow\text{ 4 dollars} \\ 1\text{ ounces }\rightarrow(4)/(5)\text{ dollars} \\ 1\text{ ounces }\rightarrow0.8\text{ dollars} \end{gathered}

Therefore, the cost of an ounce of raisin is;


0.80\text{ dollars}

The number of ounces we can get with 1 dollar can be calculated by dividing 1 dollar by the cost of one ounce;


\begin{gathered} n=(1)/(0.8) \\ n=1.25\text{ ounces} \end{gathered}

Therefore, the number of ounces we can get with 1 dollar is;


1.25\text{ ounces}
