THERE IS MORE THAN ONE :(

So the answer(s) is that they should all have 13 and Margo should give away two pounds.

Step-by-step explanation:

When you add 15+10+13+14+13=65

and then you divide them by 5 because how many numbers there are you get 13.

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
