The correct option will be : 14 years
<u><em>Explanation</em></u>
Current account balance of Susan is $1,336.60 and her initial deposit was $820
So, the amount of interest earned 
dollar
Formula for Simple Interest is: 
, where 
is the amount of interest, 
is the initial amount, 
is the rate of interest in decimal and 
is the time duration in years.
Here, 
% 
Now according to the above formula, we will get...
So, Susan has held the account for 14 years.
Answer:
it is 26.00 exactly
Step-by-step explanation:
4t+2c=200
2t+7c=400
I will solve for c in terms of t first
4t+2c=200
2c=200-4t
c=100-2t
Then I will substitute this in for c in the second equation to make it single variable
2t+7c=400
2t+7(100-2t)=400
2t+700-14t=400
300t=12
t=25
Tables cost $25 each
Plug t back into one of the ORIGINAL equations to find the cost of chairs
4(25)+2c=200
100+2c=200
2c=100
c=50
Chairs cost $50 each
Hope this helps! :)
Answer:
17:3 is 68:12 simplified
15 slices will be eaten in 10 minutes
Step-by-step explanation:
first off 17:3 is 68:12 simplified (both 68 and 12 go into 4 resulting in 17 and 3)
you have to divide 10 by 2 which will give you 5
and then multiply by 3
to get 15
Answer: 5/7
Step-by-step explanation: 7/5 is 1.4, which doesn't make sense as an answer here because it's a number greater than one, while we're looking for a number that can be made into a simple fraction, decimal or percent. 5 x 7 = 35, which also doesn't make sense for the same reasons but also because the answer is a division problem and this is multiplication. 7/7 equals one, which doesn't make sense because Melissa hasn't finished 100% of her homework yet. Therefore, the answer is 5/7.
