Question

suppose a house that costs $270,000 appreciates by 5% each year. in about how many years will the house be worth $350,000? use the equation 350 = (270) (1.05)^x and round the value of x to the nearest year.
350 = (270) (1.05)^x
1.2963 = 1.05^x
log both sides
log 1.2963 = log (1.05^x)
log 1.2963 = xlog(1.05)
x = log1.2963/log1.05
= ....
