Answer:
c≥47
Step-by-step explanation:
120+20=140
140/3≈46.667
46.667≈47
Ther can be no less than 47 cupcakes
The pertinent formula is A = P (1 + r/n )^(nt), where
P is the original amount of money (Principal),
A is the compound amount,
r is the annual interest rate, expressed as a decimal fraction,
n is the # of compounding periods per year, and
t is the # of years.
Here, A = $35000 ( 1 + 0.04/4)^(4*6)
= $35000 (1.01)^24
= $35000 (1.2697) = $44440.71
So for this you need to set them equal to each other! 3x+100=5x-160
now you combine like terms and solve!
