Answer 1

To find another expression that calculates the total amount Ella Grace spent, we can look for a way to combine the individual costs into a single expression.

The original expression for the total amount spent is: \[ (5 \cdot 20) + (3 \cdot 20) \] This can be factored as: \[ 20 \cdot (5 + 3) \] This shows that she spent $20 on each of the 5 plants and $20 on each of the 3 chairs, which totals to 8 items.

Thus, the correct alternative expression is: \[ 20 \cdot (5 + 3) \] or simply, \[ 20 \cdot 8 \]

From the options provided, the correct response is: 20⋅(5+3)
