Question

A. (A) 200b + (300s + 42d)
B. (B) 300(200b + 42d)
C. (C) 542(d + s + b)
D. (D) 300d + 200b + 42s

Answer 1

It accurately represents the total vitamin C content in the salad by summing up the contributions from dressing (42d), berries (300b), and spinach (200s). The coefficient 542 reflects the combined impact of these ingredients. Thus, the correct answer is option (C) 542(d + s + b)

Step-by-step explanation:

The correct expression for the vitamin C content in Kayson's salad is given by option (C) 542(d + s + b). This expression represents the sum of the vitamin C content contributed by each ingredient: 300 times the berries (b), 42 times the dressing (d), and 200 times the spinach (s).

In detail, the expression can be broken down as follows:

• 300b: Represents the vitamin C content from berries.
• 42d: Represents the vitamin C content from dressing.
• 200s: Represents the vitamin C content from spinach.

Adding them together (300b + 42d + 200s) gives the total vitamin C content in the salad. Therefore, option (C) accurately represents the expression for the vitamin C content in Kayson's salad.

Thus, the correct answer is option (C) 542(d + s + b)
