Answer:
![\left[\begin{array}{cc}Apples&Cost\\1&2\\2&4\\3&6\\4&8\\5&10\\6&12\\7&14\end{array}\right]](https://img.qammunity.org/2023/formulas/mathematics/high-school/mshdshw49g1ki6budkn3t6g15vihrv9om2.png)
Explanation:
If Mary bought 4 apples for $8, let's make a ratio first
Apples : cost
4 : $8
Divide by 4 on both sides
1 : $2
1 apple costs 2 dollars
Let's make a table ⬇
![\left[\begin{array}{cc}Apples&Cost\\1&2\\2&4\\3&6\\4&8\\5&10\\6&12\\7&14\end{array}\right]](https://img.qammunity.org/2023/formulas/mathematics/high-school/mshdshw49g1ki6budkn3t6g15vihrv9om2.png)
Hope this helps :)
There is no table so I created one.
Have a nice day!
