Question

Jeremy’s grandmother will add $15 to any amount that Jeremy decides to deposit in the bank. Jeremy plans to deposit between $50 and $100. The function t(j) = 15 + j models the total amount of money that will be deposited into Jeremy’s account, where j is the amount of money Jeremy deposits.

What is the practical domain of the function?

Answer 1

t(j)
`\geq` 65
and
t(j)
`\leq` 115

Answer 2

It says that j has to be between 50 and 100 so the domain would be 50≤j≤100
