The time needed to roast a chicken depends on its weight. Allow at least 20 min/lb for a chicken weighing as much as 6 lb . Allow at least 15 min/lb for a chicken weighing more than 6 lb .
a. Write two inequalities to represent the time needed to roast a chicken.

Respuesta :

The two inequalities are:

y = 20x when x ≤ 6  and y = 15x when x > 6

The scenario given here is of a chicken that is being roasted. To solve this problem, we will take y as the time required to roast the chicken and x as the lbs of the chicken. (weight)

Now two different conditions are applied depending upon the lbs of the chicken the taken to roast the chicken will vary,

20min/lb for a chicken weighs as much as 6lb.

y = 20x when x ≤ 6

15 min/lb for a chicken weighs more than 6lb.

y = 15x when x > 6

The above two equations are the two inequalities that represent time needed to roast both the chicken.
