Question

Make a table according to Kara’s Plan. Day12345 And then fill out the allowance for each day

Answer 1

Let's write two equations that represent the allowance of each person.

Kara's Plan.

She will get 1 more dollar each day, starting with 3 dollars:

`y=x+3\begin{cases}x=days \\ y=dollars\end{cases}`

Kevin's Plan.

He will get double money each day, starting with 0.25 dollars.

`z=(2^(x-1))\cdot(0.25)\begin{cases}x=days \\ z=dollars\end{cases}`

In order to get how much money Kara gets, one can substitute the number of days into 'x'.

`\begin{gathered} x\rightarrow y \\ 1\rightarrow4 \\ 2\rightarrow5 \\ 3\rightarrow6 \\ 4\rightarrow7 \\ 5\rightarrow8 \end{gathered}`
