To find another expression to calculate the total amount spent, we can factor out the common price per item, which is $20.
Since Ella Grace bought 5 plants and 3 chairs, we have:
- Total number of items: \(5 + 3 = 8\)
- Price per item: $20
Therefore, the expression to calculate the total amount spent can be rewritten as:
\[ 20 \cdot (5 + 3) \]
Among the given responses, the correct expression is:
20⋅(5+3)
So, the answer is 20⋅(5+3).
