Answer to Question #279404 in Algebra for JAKAK

Question

Ryan buys some jumpers to sell on a stall.

He spends £160 buying 60 jumpers.

He sells 80% of the jumpers for £12 each.

He then puts the rest of the jumpers on a Buy one get one half price offer.

He manages to sell half the remaining jumpers using this offer.

How much profit does Ryan make?

Answer 1

Return from 80% of jumpers sold for 12 each: $60*0.8*12=576.$

Remaining jumpers: $60-60*0.8=12.$

From these jumpers $12*0.5=6$ were sold.

From 6 jumpers 3 were sold for 12 and 3 for $12*0.5=6.$

Total return: $576+3*12+3*6=630.$

Total profit: $630-160=470.$
