Answer:
Well the whole answer is 10.246950 smth smth but I don’t have the multiple choices so your gonna have to round yourself 
Step-by-step explanation:
Okay so you have a weigh of 8 and a diagonal of 13. 
If you look, theres a triangle there. One side has 8 and the diagonal that was cut forms a 13. So we have a leg and a hypotnuse. To find the other leg (length) just follow the Pythagorean theroum and solve for b or a.
Pythagorean theroum: a^2+b^2=c^2
Now subsitute c for 13 since its the hypotnuse and a or b as 8 but only one. 
In this case I’m substituting a for 8.
8^2+b^2=13^2
Solve the squares 
64+b^2= 169
Isolate the b
b^2=105
Now square root 105 
√105 will give the answer above on a normal calculator but if you have to round, I don’t know what place but you can round.
 
        
             
        
        
        
2.99% x 5 = 167.22
10,500.00 + 167.22 = 10,667.22
