Selena wants to sell hot dogs at a local sports arena. She must pay a fee of $25 $25 to sell hot dogs and estimates each hot dog will cost her $0.75 $0.75 . Selena plans on selling each hot dog for $2.00 $2.00 . What is the minimum number of hot dogs ( x x ) Selena needs to sell for the revenue to be greater than or equal to her cost?

Respuesta :

Answer:

20

Step-by-step explanation:

Let the cost of 1 hot dog be $x.

2x ≥ 25 + 0.75x

2x - 0.75x ≥ 25

1.25x ≥ 25

x ≥ 20
