The price of pork bellies fell by 50%. Days later, the price fell again (from the lower price) by another 25%. If the price of pork bellies is now $.75 per pound, what was the original price? thank you
⚡️
Call the original price, P
So
P ( 1 - .50) ( 1 - .25) = .75
P (.50) (.75) = .75 divide both sides by .75
P (.50) = 1
P = 1 / .50 = 2 ( dollars)
Thank you
