Answer:
Step-by-step explanation:
-7k = 0
Divide both sides by (-7)
k = 0
17) c - 4 = -23
Add 4 to both sides
c - 4 + 4 = -23 + 4
c = - 19
Answer:
DA= $800 and DB= $1200
Step-by-step explanation:
Equation I (Interest of Bank A):
IA= 0.06/year*DA *1year (DA= Deposit in Bank A)
IA= 0.06*DA
Equation II (Interest of Bank B):
IB= 0.08/year*DB *1year (DB= Deposit in Bank B)
IB= 0.08*DB
Total interest:
TI=IA+IB=$144
Total deposit:
TD= DA +DB= $2000
Adding equations I and II:
IA+IB = 0.06DA +0.08DB
$144= 0.06DA+0.08DB
(DB= $2000-DA)
When replacing DB:
$144= 0.06DA + 0.08($2000-DA)
Applying distributive property:
$144= 0.06DA + (0.08*$2000) -0.08DA
$144= -0.02DA + $160
0.02DA= $160-$144
0.02DA = $16
DA= $16/0.02
DA= $800
DB= $2000-$800
DB= $1200
I believe the answer is 70! :) hope it's right!
