The manufacturing cost of a cell phone was $124. Sellers first marked up the cost by 20 percent. Sales were poor, so sellers decreased the markup to 15 percent. Calculate the old and new selling prices.
So what do you know about percentages?
from 20 decreased to 15
No, percentages in general. Percentages are the number given over 100. So 20% = 20/100
old prices add $124 by 20%=
new price $124 +15%=?
right i understand so.. here are my answer choices a- old price 170.00 new price 148. b- old 142.60 new 148.80 c- old 148.80 new 142.60
So do the calculations... \[(124*20/100)+124= price old\]
i got 124.15 but not sure if thats right @juana02
thats wrong
so 148.80 old and (124*15/100)+124= 142.60 :) hmmm looks good right?
