Answer:
The actual answer is 9.25
Step-by-step explanation:
The mistake is in Step 4, as <u>4 × 2 = 8</u>, not 6
-6z = 72
Divide both sides by -6
-6z = 72
/-6 /-6
z = -12
Answer:
11 X 34 then divide that by two which is 187
Step-by-step explanation:
Answer:
The interest is 4,500
Step-by-step explanation:
We use the simple interest formula,
I = Prt
where
I = interest
P = principal amount = 12,500
r = interest rate = 12% = 0.12
t = time = 3 years
I = Prt
I = 12,500 × 0.12 × 3
I = 4,500
