Pilar is starting a small business that
makes specialized stationery. She finds
that producing larger quantities of a
design saves her money. Each print run
costs $50 plus $2 for each item. If y
dollars is the cost and x is the number of
items, this statement can be represented
by y = 2x + 50. She can sell each item for
$4.50. So her revenue, y, is equal to 4.5
times the number of items: y = 4.5x. The
solution of this system of equations is
her break-even point.

20

Step-by-step explanation:

We have two simultaneous equations.

(1)  y = 2x + 50

(2) y = 4.5x

1. Subtract (1) from (2)

0 = 2.5x - 50

2. Add 50 to each side

2.5x = 50

3. Divide each side by 2.5

x = 20

Pilar must sell 20 items to break even.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
