At the end of the first fiscal quarter, which ended on the last day of last month, the research team at Finer Diner computed the following model as a means of predicting monthly gross revenues:

Gross revenues (Y) = 618.4 + 282.68(Advertising Expenditures) + 95.43(Number of Nights with Live Entertainment)

Y = Gross revenues (monthly)

X1= Advertising Expenditures (monthly)

X2= Number of Nights with a Band Present (monthly)

Calculatedp-values for Advertising Expenditures and Number of Nights with Live Entertainment are 0.00005 and 0.35 respectively.

Currently, the restaurant spends $500 per month on advertising and has live entertainment fifteen nights per month.

Based on the current model andp-values:

Predictgross revenues if the restaurant raised monthly advertising expenditures by 15%, 25%, and 50%.

Predictgross revenues if the restaurant provided live entertainment 12 nights per month, 20 nights per month, and 24 nights per month.
