Answer:
$1296
Step-by-step explanation:
the markup is 700 so add that to the 500, then sales tax adds 96
Only the top one is equivalent to c/(13a)
The rule is (a^b)/(a^c)=a^(b-c)
We'll use the notation 
for the principal value and 
for all the values:
Part I
Part II. In our range we can write
Part III.
Part IV.
31/20, or turned into a mixed fraction, is 1 11/20kg. Hope this helps!
To solve this we need to figure out what 7.5% of 15,500 is. (It’s 1162.5). Now we know that after one year it is a total of 16,662.5. We then figure out what 7.5% of 16,662.5 is, which is 1,249.6875. You then add that to 16,662.5 which comes out to 17,912.1875. We then figure out 7.5% of that is 1,343.4140625. We then add that to the last total which is 19,255.6015625 and we simplify that to 19,256 and we find out that the final total is $19,256. But it wants how much have we earned which means we need to subtract the original from the new, which is 3756 and we add a unit.
Meaning the final answer is $3,756.
