Jackson’s car was making a rumbling noise for two weeks. He decided to take it to the mechanic to get it checked out. To diagnose the problem, the mechanic tells Jackson that he charges a flat fee of $60 and $35 for each hour he spends trying to identify the problem.



Write a linear equation in ​y = mx+b​ form to represent the cost of getting Jackson’s car diagnosed.



A.
y = 35x + 60

B.
y = 60x + 35

C.
y = 95x

Respuesta :

Answer:

The correct answer is A

Step-by-step explanation:

Y=The total cost including the flat fee

m=35 (cost per hour)

x= the unidentified hours it will take him

b= the on time flat fee that is added to the total

Final equation: y=35x+60

The linear equation in ​y = mx + b​ form to represent the cost of getting Jackson’s car diagnosed is;

Option A; y = 35x + 60

The linear equation form is given as;

y = mx + b

where;

m is slope

b is y-intercept which is the value of y when x is zero

We are told that the mechanic charges a flat fee of $60. This means before any hours which we will call x, the cost (y) is $60. Thus;

b = 60

We are told that the mechanic charges $35 per hour. Thus, the slope will be 35 as it represents cost(y) per hour(x).

Thus, the linear equation will be;

y = 35x + 60
