An algebraic expression is an expression that contains one or more numbers, one or more variables, and one or more arithmetic operations.
A. $(3 + 2n)
B. $(5n + 2)
C. $ n
D. $(5 - 2n)
Correct Answer: A
Step 1: $5 for the first day and $2 extra for every additional day.
Step 2: Sarah would pay $5 + (n - 1) × $2 for renting a video cassette for n days.
Step 3: So, the algebraic expression that corresponds to the amount that Sarah would pay is $(3 + 2n).
