Answer:
26
Step-by-step explanation:
5y-3+2y+1=180
7y-2=180
7y=182
y=26
200,000 = 158,000(1.06)^x
Divide both sides by 158,000
1.2658 = 1.06^x
Take the log of both sides and use the power rule to bring down the exponent (x) to the front.
log 1.2658 = x log 1.06
Divide both sides by log 1.06
log (1.2658)/log(1.06) = x
x = 4 years
CHECK
y = 158,000(1.06)^4
y = 199,471.36
The probability is 1/5, 1:4(favorable), or 4:1 (unfavorable)
Hope this helps
