Let E = total earnings per month and x represents the number of items sold.

Since the expression 5x + 350 is the earnings per month, this means E = 5x + 350.

We want the earnings (E) to be "at least 950", which means we want E to be equal to 950 or larger. So we can say

E >= 950

The symbol ">=" without quotes means "greater than or equal to"

Replace the "E" with "5x+350" and solve for x

E >= 950
5x+350 >= 950
5x+350-350 >= 950-350
5x >= 600
5x/5 >= 600/5
x >= 120

So you are close, but the answer is choice C. This means she must sell 120 items or more.

The figure shows a circle with center P and inscribed isosceles Triangle ABC. If AC has the same length as the radius of the cir

Ksenya-84 [330]

Answer:

<ABC = $30^{0}$ (The central angle of a circle is twice any inscribed angle subtended by the same arc).

Step-by-step explanation:

From the diagram, ABC is an inscribed isosceles triangle. But the radius of the circle equals the length AC.

Join P to A and C to form an equilateral triangle. An equilateral triangle has equal sides and angles. So, the value of each interior angle of the equilateral triangle is;

Sum of angle in a triangle = $180^{0}$
