When the given quantity consists of several denominations, and the price relates to the highest of those denominations, work by RULE 8. Multiply the price by the numoer of the highest denomination in the given quantity, and the product will be the value thereof; to which add the value of the remaining deno ninations, found by taking parts of the price: or, Find the value of the number of the highest denomination by one of the preceding rules, to which add the value of the remaining denominations, found as before.
