Question

Pls help me i dont understand

Answer 1

Answer is equation C = .60t + 3

Step by step

C = We know the total charge is $6

m = We know the price per minute is .60

t = We know the variable (minutes) is 5

Using slope intercept formula

y = mx + b is our formula

Fill in the known values to find b

$6 = .60(5) + b

b is our unknown, the starting cost or constant, the base charge for using the computer regardless of minutes

$6 = .60(5) + b
Multiply

$6 = 3 + b
Subtract 3 from both sides to solve for b

$6-3 = 3 - 3 + b
Simplify

$3 = b

Now we can write our equation

C = .60t + 3

Answer 2

Let's call the initial fee "x". The equation for the total cost of using a computer for t minutes at the internet cafe can be expressed as:

C = x + 0.60t

Knowing that the total charge to use a computer for 5 minutes would be $6, we can use this information to find the value of x:

C = x + 0.60 * 5

6 = x + 3

x = 6 - 3

x = 3

So, the equation representing the total cost of using a computer for t minutes at the internet cafe is:

C = 3 + 0.60t
