-The Lopez brothers, Angelo, Antonio, and Isaiah, own the Lopez Cantina. Angelo is in charge of marketing, and he is developing his sales forecast for next year. Because of his marketing efforts, he predicts a 5 percent increase in his monthly guest counts. Angelo is not aware of any anticipated menu price increases and assumes, therefore, that his weighted check average will remain stable. A. Using last year's sales and guest counts, estimate Angelo's weighted check average (average sales per guest) for the year. (Spreadsheet hint: Use the ROUND function to two decimal places on the cell containing the weighted check average, cell D18, because it will be used in another formula in part B.)

Using the weighted check average calculated in part A, determine Angelo's projected sales assuming a 5 percent increase in guest counts. (Spreadsheet hint: Use the ROUND function to zero decimal places in the Guest Count Forecast column, cells C23:C34. Use the SUM function for the total, cell C35. Otherwise, your answers will not be correct.)
