Which statement is a counterexample for the following conditional? if you live in springfield, then you live in illinois. a.) erin naismith lives in springfield, massachusetts. b.) billy jones lives in chicago, illinois. c.) sara lucas lives in springfield. d.) jonah lincoln lives in springfield, illinois

Counter example means any example that is the opposite or contradicts the given theory.

Here, it is given that if any person lives in Springfield, then he lives in Illinois.

All options except A are true. Chicago is in Illinois and other two options are also correct. They state the true example.

Only example A.) Erin Naismith lives in Springfield, Massachusetts contradicts as Springfield is not in Massachusetts.

Hence, option A is your answer.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
