A music store buys instruments and then sells them for 30%more than they paid.
If the store buys a guitar for $45, what will the store sell it for?
Thank you!
so you would work out 10% which is 1 decimal place so that would be 4.5 then you would multiply it by 3 to get 30% and add it on so 4.5+4.5+4.5=13.5 then do £45 + £13.50
