How many items must she sell to break even?

Mathematics
1 answer:
nikklg [1K]3 years ago
8 0

Answer:

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.
