A restaurant offers a $12 dinner special that has 7 choices for an appetizer, choices for an entrée, and 3 choices for a dessert. How many different meals are available when you select an appetizer, an entrée, and a dessert?

21x,

where x = number of entrees

Step-by-step explanation:

appetizer choices: 7

choices for an entree: x

choice for dessert: 3

Total number of combinations:

7 * x * 3 = 21x

Since the number of choices of entrees is missing, the best answer you can get is 21x, where x is the number of entrees.

Replace x with the number of entrees to get your final answer.

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

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
