For each filing segment, indicate in the table whether a cross-reference is needed. Then scroll down to the blank rows at the bottom of the table and fill in the necessary cross-references, in order, starting with the first blank row of the table. For each cross-reference, in the far left column of the table, fill in the original filing segment number followed by X. (For example, a cross-reference for filing segment 1. Would be labeled 1X). Then, fill in the filing segment and key units. Then , for each cross-reference, fill in the cross-reference note (“SEE…” or “SEE ALSO…”) in the column on the far right of the table. See the example filing segment and scroll down to see it’s corresponding cross-reference example.

I need assistance with the following MySQL question:  Create a stored procedure named prc_inv_amounts to update the INV_SUBTOTAL, INV_TAX, and INV_TOTAL. The procedure takes the invoice number as a parameter. The INV_SUBTOTAL is the sum of the LINE_TOTAL amounts for the invoice, the INV_TAX is the product of the INV_SUBTOTAL and the tax rate (8 percent), and the INV_TOTAL is the sum of the INV_SUBTOTAL and the INV_TAX.   Screenshot attached*

The InstantRide User Satisfaction team received a phone call from a user who might have left her wallet in the car. She indicated that the license plate of the car was starting with BB-883 but unfortunately, she could not remember the full license plate number. The team wants to get all travel information for the cars with the license plate starting with BB-883. You need to return all travel data from the TRAVELS table for the CAR_ID which has a plate number compared with SUBSTR and UPPER functions.
