This one u probably have to choose more than one

Replace with 27, solve for , and see if the result is a whole number.

27 = 2a   ⇒ = a not a whole number  NO

27 = 2a + 1  ⇒  26 = 2a  ⇒  13 = a  13 is a whole number  YES

27 = 3a  ⇒  9 = a   9 is a whole number  YES

27 = 3a + 6   ⇒   21 = 3a   ⇒   7 = a   7 is a whole number  YES

27 = 3a + 1   ⇒   26 = 3a   ⇒   = a not a whole number  NO

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
