Ms. harris is stocking up on dry-erase markers for the upcoming school year. she used 56 dry-erase markers last year and plans to use at least that many for next year. the number of markers in each box is two more than three times the number of boxes she purchased for this upcoming school year. which of the following inequalities can be used to determine b, the number of boxes she purchased.

Step-by-step explanation:

Here, b represents the number of boxes she purchased for this upcoming school year,

Also,  The number of markers in each box is two more than three times the number of boxes she purchased for this upcoming school year.

⇒ The number of marker in each box = 3b+2

Now, the total number of marker = Number of boxes × Number of marker in each box

Since, she plan to use at least 56 marker in the upcoming year,

That is, the total number of marker ≥ 56

Which is the required inequality that shows the given situation.

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
