Answer:
$400
Step-by-step explanation:
The formula for simple interest is i = p * r * t, where r is the annual interest rate as a decimal fraction, p is the principal and t is the time in years.
Here we want to determine what the principal was. Solving the above equation for p, we get:
i $64
p = --------- = -------------- = $400
r * t (0.08)(2)
Answer:
2
Greatest common factor (GCF) of 16 and 26 is 2. GCF(16,26) = 2
1. set up the problem5 x 2/3
2. put a 1 on 5 to make it a fraction5/1 x 2/3
3. multiply and divide(5 x 2) / (1/3)
4. find out the answer10/3
5. turn the answer into a mixed fraction10 divided by 3= 3.1 3 stays the same you don't need to say 1
6. it equals3 1/3
7. so the answer is3 1/3
