You pay $30 each month for satellite tv, plus $2.50 for every movie you purchase. write and solve an equation to find the number of movies purchased during a month with a total bill of $45.

6 movies

Step-by-step explanation:

You pay each month for satellite TV = $30

and for every movie you purchase = $2.50

Let the number of the movies you purchase be x

The equation will be

30 + 2.50x = 45

2.50x = 45 - 30

2.50x = 15

x =

x = 6

You purchased 6 movies during the month.

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
