A statistician develops a model to determine a company’s monthly online sales based on the amount it spends on online advertising. Using this model, y=128.9+171.5x , how much should the company expect in monthly online sales if it spends $350.00 on online advertising?(1 point) Responses $300.40 $300.40 $60,153.90 $60,153.90 $45,286.50 $45,286.50 $60,025.00

1 answer

To calculate the expected monthly online sales based on the advertising spend using the given model \( y = 128.9 + 171.5x \), we need to substitute \( x \) (the amount spent on online advertising) with $350.00.

Using the formula:

\[ y = 128.9 + 171.5 \cdot (350) \]

Now, calculate \( 171.5 \cdot 350 \):

\[ 171.5 \cdot 350 = 59,025 \]

Now, substitute this back into the equation:

\[ y = 128.9 + 59,025 \] \[ y = 59,153.9 \]

So, the expected monthly online sales if the company spends $350.00 on online advertising is $59,153.90.

None of the provided options match this result exactly, so if required to choose from the offerings, double-check on possible rounding or interpretation discrepancies in the problem context. However, according to the calculations based on the model, the correct answer is:

$59,153.90
