Answer:
The money was invested for 8 years.
Step-by-step explanation:
Given that a principal of $ 20,000 is invested at 6.25% and earns $ 10,000 simple interest, to determine how many years has the money been invested, the following calculation has to be performed:
(20,000 x 0.0625) x X = 10,000
1,250X = 10,000
X = 10,000 / 1,250
X = 8
Thus, the money was invested for 8 years.
Answer:
x = 30
Step-by-step explanation:
-2x + 10 +4x=70
-10 -10
-2x + 4x = 60
2x = 60
/2 /2
x = 30
