Pedro works as a newspaper deliverer. he receives a base pay plus an additional amount per newspaper delivered. last week, pedro delivered 5 newspapers and earned $37.50. this week, he delivered 20 newspapers and earned $75. let x equal the number of newspapers pedro delivers and y be the earnings he receives in dollars. which linear function models the scenario?

The required linear function is,

y = 2.5x + 25

Step-by-step explanation:

Here, x represents the number of newspapers Pedro delivers and y represents the earnings he receives in dollars.

Let the linear function that represents the given situation is,

y = mx + c,

Given,

When x = 5, y = 37.50,

⇒ 37.50 = 5m + c (1),

Also, When x = 20, y = 75,

⇒ 75 = 20m + c (2),

Equation (2) - Equation (1),

We get,

37.50 = 15m

⇒ m = 2.5

From equation  (1),

37.50 = 12.5 + c

⇒ c = 25

Hence, the linear function that models the given scenario is,

y = 2.5x + 25

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
