Final answer:
By comparing the letter codes from the words TOUR, CLEAR, and SPARE, the numerical code for CARE is determined to be 5847 based on the pattern established.
Step-by-step explanation:
The student's question involves decoding words given their numerical representations. By analyzing the codes given for TOUR, CLEAR, and SPARE, we can decipher the code for each letter and then apply it to find the code for CARE. From the examples, we can deduce that T is 1, O is 2, U is 3, R is 4, C is 5, L is 6, E is 7, A is 8, S is 9, and P is 0. Therefore, the code for CARE would be constructed by finding the numerical code for each of its letters, which are C(5), A(8), R(4), and E(7). The correct code for CARE is 5847, or option d.
