Answer:
a) $4000
b) $2000
Step-by-step explanation:
a)
interest = Principal x rate as decimal x time
interest = 20,000 x 0.05 x 4
interest = 4000
b)
interest = Principal x rate as decimal x time
interest = 20,000 x 0.05 x 2
interest = 2000
you save $2000 if you pay after 2 years

Step-by-step explanation:
Answer:
x = length of sitcoms = 21 minutes
y = length of dramas = 42 minutes
Step-by-step explanation:
Let
x = length of sitcoms
y = length of dramas
6x + 6y = 372 (1)
2x + 6y = 288 (2)
Subtract (2) from (1) to eliminate y
6x - 2x = 372 - 288
4x = 84
x = 84/4
x = 21
Substitute x = 21 into (1)
6x + 6y = 372
6(21) + 6y = 372
126 + 6y = 372
6y = 372 - 126
6y = 246
y = 246/6
y = 41
x = length of sitcoms = 21 minutes
y = length of dramas = 42 minutes
