Answer:
11314.87379 (This is still rounded).
Step-by-step explanation:
Year 1:
9300*4%=372. 9300+372=9672.
Year 2:
9672*4%=386.88. 386.88=10058.88.
Year 3:
10058.88*4%=402.3552. 402.3552+10058.88=10461.2352.
Year 4:
10461.2352*4%=418.449408. 418.449408+10461.2352=10879.68461
Year 5:
10879.68461*4%=435.1873843. 435.1873843+10879.68461=11314.87379.
 
        
             
        
        
        
Answer:
1. d  2. a  3. d  4. a  5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d. 
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times. 
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120. 
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108. 
 
        
             
        
        
        
So,
If you do some simple division, you will find how much each cm costs in each cake.
20cm cake = 67.5 cents/cm
25cm cake = 93.75 cents/cm
Assuming that you cannot order fractions of cakes, the best deal would be to order 5 of the 20cm cakes.
Cost = 13.50 * 5 = $67.50
You will have to pay $67.50 for the cakes if you want the best deal.
