Final answer:
Bob collects 4 times the number of seashells Tails collects plus 3 more, so the expression is 4x + 3, where x is the number of seashells Tails collects.
Step-by-step explanation:
The student asks to find the expression that represents the number of seashells Bob collects, given that Bob collects 3 more than 4 times the number of seashells Tails collects.
If we let x represent the number of seashells that Tails collects, then the expression for the number of seashells Bob collects would be 4x + 3.
This is because Bob collects 4 times whatever Tails collects (4x) and then 3 additional seashells (+ 3).
