If Chad can paint the whole room in 5 hours, in 1 hour he gets 1/5 of it painted.  If Cassie can paint the whole room in 3 hours, in 1 hour she gets 1/3 of it painted.  If we add those together we can find out how much of the room they can paint together in one hour.  1/5 + 1/3 = 1/x, with x being the number of hours it will take them to paint the room together.  Common denominator is 15, therefore, 3/15 + 5/15 = 1/x and 8/15 = 1/x.  Cross-multiply to get 8x = 15, so it will take them 15/8 hours, or 1.9 hours to paint the whole room together.

Help me with this please
Reika [66]

Answer:

$2,459.21

Step-by-step explanation:

(see attached for reference)

recall that the formula for compound interest is:

A = P [ 1 + (r/n)^ (nt) ]

where,

A = Final amount ( we are asked to find this)

P = principal amount = given as $2,340

r = Annual Interest Rate = given as 5% = 0.05

n = number of times compounded in a year = 4 (compounded quarterly)

t= time = 1 year

Substituting the values into the equation,

A = P [ 1 + (r/n)^ (nt) ]

A = 2,340 [ 1 + (0.05/4)^ (4·1) ]

A = $2,459.21
