Simple Interest Rate Formula:
- A is final amount
- P is principle (initial) amount
- r is rate
- t is time (in years)
Step-by-step explanation:
<u>Step 1: Define</u>
P = 7200
r = 0.75% = 0.0075
t = 5
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute in variables [Simple Interest Rate Formula]:
- (Parenthesis) Add:
- Evaluate exponents:
- Multiply:
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.
