1550.28 – Swerve's Bikes and Skateboards
Swerve, the local bicycle store, bought some used bikes and skateboards to overhaul and re-sell. If they paid an average of $55 per bike and $22 per skateboard, AND if they bought twice as many bikes as skateboards, AND if they spent a total of $660, how many of each did they buy?
Let be the number of skateboards and be the number of bikes.
Then Swerve paid for the skateboards and for the bikes.
And all of that comes out to $660$, thusly:
so . That's 5 skateboards and 10 bikes.
Note: for anyone worrying about the "average" price, it just means you can assume they were all the same price and it all comes out OK--$55 for each bike and $22 for each skateboard.
