Question

If Sears Roebuck sells six times as many batteries as Firestone, and their difference in

sales is 250,000 batteries, how many batteries did each sell?

Answer 1

• Let Firestone sells x
• Roebuck sells 6x

AtQ

`\\ \sf\longmapsto x+6x=250000`

`\\ \sf\longmapsto 7x=250000`

`\\ \sf\longmapsto x=(250000)/(7)`

`\\ \sf\longmapsto x\approx 35714`
