On Saturday, Spencer went to play at his neighborhood park. Spencer rode the new bicycle that he had gotten
on his birthday.
When Spencer got to the park, he saw that there were 10
bicycles and tricycles altogether. If the total number of
wheels was 23, how many were bicycles and how many
were tricycles?

step-by-step explanation:

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
