Final answer:
To solve for all the possible combinations, we need to find sets of three integers for small, medium, and large cakes such that their total price is $41, and they add up to 11 cakes. This involves using diophantine equations to explore combinations that meet the price and quantity constraints.
Step-by-step explanation:
The student asks for all possible combinations of small, medium, and large cakes that can be bought with $41, considering the prices ($3, $5, $7 respectively) and the total number of cakes needed, which is 11. This is a classic example of a problem that can be solved using the diophantine equations in mathematics, catering to combinations and permutations based on given constraints.
We need to find combinations of the variables s (small cakes), m (medium cakes), and l (large cakes) that satisfy the following system of equations:
- 3s + 5m + 7l = 41 (Total cost equation)
- s + m + l = 11 (Total number of cakes equation)
It's a matter of iterating over possible values of s, m, and l while keeping the equations consistent. We are looking to find positive integer solutions because you can't purchase a fraction of a cake. Through a systematic approach, we can list out all potential combinations that meet the criteria.
Bold example:
One possible combination could be buying 2 small cakes, 3 medium cakes, and 6 large cakes since (2*3)+(3*5)+(6*7) equals $41 and 2+3+6 equals 11 cakes in total.
