1. Write a formula that would return a TRUE result if the sum of the first five numbers in a column of data are negative (for example, if you wanted to quickly know if the column had more expenditures than income). 2. Provide an example of a common business-related task or problem (payroll, inventory management, budgeting, profit-loss statements, etc.) that benefits from the use of cross-sheet referencing.

3. Provide an example of formula (with proper syntax) that would check whether cell B5 has a negative number and return a value of “negative” if it was and “not negative” the value was zero or higher.

Consider the following declarations (1, 2, 3, 5, 7)class bagtype{public: void set(string, double, double, double, double); void print() const; string getstyle() const; double getprice() const; void get(double, double, double, double); bagtype(); bagtype(string, double, double, double, double); private: string style: double l; double w; double h; double price; }; a.) write the definition of the number function set so that private members are set according to the parametersb.) write the definition of the member function print that prints the values of the data membersc.) write the definition of the default constructor of the class bagtype so that the private member variables are initialized to "", 0.0, 0.0, 0.0, 0.0, respectively d.) write a c++ statement that prints the value of the object newbag.e.) write a c++ statement that declares the object tempbag of type bagtype, and initialize the member variables of tempbag to "backpack", 15, 8, 20 and 49.99, respectively
