Melanie is running a regression analysis to predict unit sales in the central Asian region for MARS products, specifically pet food. Here's her output from R:

Variable

Coefficient Estimate

p$-$value

Intercept $($Constant$)$

$1,344$

$\mathrm{.}03$

Promotion

$240$

$\mathrm{.}02$

In$-$Store Display

$314$

$\mathrm{.}58$

Direct Mail

$454$

$\mathrm{.}001$

Social Media Ad

$1,544$

$\mathrm{.}49$

If the variables each represent either bring present $(1)$ or not $(0),$ and Melanie is trying to predict the unit sales of a store that would have all the elements present, what would the estimated sales be for this store?

Question $4$ options:

About $2,038$ units

About $$5,000$

About $3,896$ units

About $694$ units

About $$7,500$
