yee
Did you not think that $41.25 would be a ridiculous answer????
cost 3 years ago was 4 / 1.25 = $3.20
check:
increase of 25% of 3.20 = 80 cents
new cost = 3.20 + .80 = $4.00
cost 3 years ago was 4 / 1.25 = $3.20
check:
increase of 25% of 3.20 = 80 cents
new cost = 3.20 + .80 = $4.00
umm D is correct
idk what ur talking about
