### Subject: Basic Math

If you have a shipment of tennis balls coming in and each shipment holds 30 tennis balls and each day you get 7 shipments, how many tennis balls would you have after 1 year, if you sell 15 tennis balls a day

each shipment hold 30 tennis balls and you get 7 of those a day so 30 multiplied by 7 is 210. so 210 tennis balls a day for 1 year is 210 multiplied by 365 is 75,600 tennis balls a year. but since you sell 15 tennis balls a day thats 15 multiplied by 365 which is 5,475 tennis balls sold a year. Then you subtract 5, 475 from 75,600 which is 70, 125 tennis balls
