Answer:
64.96
Step-by-step explanation:
The most common benchmark percents are 
and 
We are given 
which is closest to 
.
Now we calculate 
which is equal to 
.
We are left with 
more to add.
We can say 
Therefore 
Now add the two.
Thus 64.96 is the answer.
Answer: A. 724
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! :)
