The question says a ball and a bat cost 4000 USD together. The shop sold the bat at a profit of 30% and the ball at a loss to 15% for 4500. Find the cost of the individual items. I don't know how to approach this problem.
The second equation should be:I worked out the naming part but not sure how to proceed,
L+T=4000 and
(L+30%)+(T-15%)= 4500
what next?
Makes more sense that way, thanks. Now we're stuck with 1.3L+0.85T=4500 though. I just can't see a way to eliminate either L or T to get one of them.....The second equation should be: L*(1+0.30) + T*(1-0.15)= 4500 Do you see why?

You never add 30% or subtract 15%. You add 30% of something and subtract 15% of something! Think what 55 + 30% would equal. It makes no sense at all!I worked out the naming part but not sure how to proceed,
L+T=4000 and
(L+30%)+(T-15%)= 4500
