How would I write this Spanish sentence using the future tense?

How would I use the future tense of the verb in parenthesis to complete the sentence?

Ella ________ una actitud positiva en todo lo que haga. (mantener)

Also, did I do this one right?
El lunes, Amanda y yo _______ a pasear por la isla. (salir)
I put "Amanda y yo saldremos".
