Answer:

C

Step-by-step explanation:

"At least 75" means Erin needs a score that is 75 <u>or more</u>.  Her score should be equal to or greater than 75.

The number line that shows this is C because the point at 75 is filled in (showing that 75 is included), and the ray (arrow) extends to the right indicating numbers larger than 75.

Edgar Anderson earns $300 a week plus a 15% commission on all sales over $1,000. If Mr. Anderson's sales for one week are $2,500
Temka [501]
Basic amount that Edgar Anderson earns per week = $300
Sales of Mr. Anderson for one week = $2500
Percentage of commission on sales above $1000 = 15%
Then
Amount of commission
earned for the week = [2500 - 1000] * (15/100) dollars
                                 = 1500 * (15/100) dollars
                                 = 15 * 15 dollars
                                 = 225 dollars
Then
Gross pay of Edgar Anderson for the week = (300 + 225) dollars
                                                                     = 525 dollars
So the gross pay of Edgar Anderson for the week is $525.

Find a1, for the given geometric series. Round to the nearest hundredth if necessary. Sn= 86,830, r= 2.2, n=4
larisa86 [58]

Answer:

4,646.30

Step-by-step explanation:

The sum of n terms of geometric sequence can be calculated using formula

S_n=\dfrac{a_1(1-r^n)}{1-r}

In your case,

S_n=86,830\\ \\r=2.2\\ \\n=4\\ \\a_1=?

Substitute into the formula:

S_4=\dfrac{a_1(1-2.2^4)}{1-2.2}\\ \\86,830=\dfrac{a_1(1-23.4256)}{-1.2}\\ \\-104,196=a_1(-22.4256)\\ \\22.4256a_1=104,196\\ \\a_1=\dfrac{104,196}{22.4256}\approx 4,646.30
