5⋅(20+3)
5 times open paren 20 plus 3 close paren

20⋅(5+3)
20 times open paren 5 plus 3 close paren

(5+20)⋅(3+20)
open paren 5 plus 20 close paren times open paren 3 plus 20 close paren

5⋅20⋅3

Answer 1

The total amount Ella Grace spent can also be expressed as \(20 \cdot (5 + 3)\). This expression simplifies to her total expenditure of $20 for each item, multiplied by the total number of items she bought (5 plants + 3 chairs = 8 items).

Therefore, the correct alternative expression to calculate the total amount spent is:

20⋅(5+3)

This corresponds to the response:

20 times open paren 5 plus 3 close paren.
