This is a table with 6 lines.
In each line, the number in the first column is the 'x' value.

All you have to do on each line is ...

--- substitute the 'x' value in (100 + 23x), simplify it,
and write the result in the middle column

then

--- substitute the 'x' number in  90(1.2ˣ) , simplify it,
and write the result in the last column.

On the first line, x=0.

100 + 23x  =  100 + 0 = 100.  Write 100 in the middle column.

90(1.2ˣ) = 90(1) = 90.  Write 90 in the last column.

Then go on to the second line, where x=1.

You'll make it.
