The time it takes them working together to paint the room is 3.08 hours
<h3>Rational expression</h3>
Rational expression are equation written as a ratio of two expressions or equations.
If Wes can paint a certain room in 8 hours, she can paint 1/8 of the room in 1 hr
Similarly, if Sally can paint the same room in 5 hours, , she can paint 1/5 of the room in 1 hr
Determine the time it takes them to paint the room altogether.
Time together = x
Using the expression below to determine the value of x
1/x = 1/8 + 1/5
1/x = 5+8/40
1/x = 13/40
x = 40/13
x = 3.08
Hence the time it takes them working together to paint the room is 3.08 hours

Answer:
12 years
Step-by-step explanation:
From the formula;
A = P(1 + r)^n
A = Amount = $2733.19
P = Principal = $2150
r = rate = 2%
n = time in years = ???
2733.19 = 2150(1 + 0.02)^n
2733.19/2150 = (1 + 0.02)^n
1.27 = (1.02)^n
Taking logarithm of both sides
log 1.27 = n log 1.02
n= log 1.27/log 1.02
n= 0.1038/0.0086
n = 12 years
