Question

Ruby bought an animal bank for her nephew. She is the only one who puts money in the bank, and no money is taken out. The function f (v) = 10 + 2v describes the amount in the bank after v visits with her nephew. Which statement is true?

a) Ruby puts $2 in the bank each visit.

b) Ruby puts $10 in the bank each visit.

c) There was $2 in the bank before the first visit.

d) There was $12 in the bank before the first visit.

Answer 1

The correct statement is that Ruby puts $10 in the bank each visit.

Step-by-step explanation:

The function f(v) = 10 + 2v describes the amount in the bank after v visits with her nephew. Let's analyze the function:

1. The constant term 10 represents the initial amount of money in the bank before any visits with her nephew.
2. The coefficient of 2 represents the amount of money Ruby puts in the bank during each visit.

Based on this analysis, the statement "Ruby puts $2 in the bank each visit" is incorrect (a)). The correct statement is "Ruby puts $10 in the bank each visit" (b)). Therefore, option b) is the true statement.

Answer 2

The answer is Ruby puts $10 in the bank each visit.
