Melissa runs a dog-boarding service. The cost to board a dog for one day is $25.00. If the same dog owner wants to board their dog for more than one day, the cost is $15.00 per additional day. Jared plans to use Melissa's dog-boarding service, and he budgets to spend no more than $150.00 to board his dog.

25 + 15x ≤ 150

Step-by-step explanation: For this problem we will write an inequality to represent this situation.

Let x equal each additional day.

25 + 15x ≤ 150

The inequality above states that the dog owner will spend $25 for the first day and then for each additional day the dog owner will spend $15, but is budget is no more than $150 that the dog owner can spend.

8 days

Step-by-step explanation:

Cost = 25 + 15n

25 + 15n《150

15n《125

n《8.3333333333

At max, 8 days

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
