The cost of taking a cab is $4 plus $0.75 per mile. This can be represented using the linear function c=0.75m+4

Question

𝑐
=
0.75
, where c is the cost per trip and m is the distance in miles. Graph the equation on a coordinate plane. Based on your line, what would the corresponding dependent variable be if you were to travel 4.5 miles? Round your answer to the nearest hundredth.(1 point)

Answer 1

To find the cost of taking a cab for traveling 4.5 miles using the given linear function \( c = 0.75m + 4 \), we can substitute \( m \) with 4.5:

\[ c = 0.75(4.5) + 4 \]

Calculating that step by step:

1. First, calculate \( 0.75 \times 4.5 \): \[ 0.75 \times 4.5 = 3.375 \]

2. Next, add 4: \[ c = 3.375 + 4 = 7.375 \]

Now, rounding to the nearest hundredth, we get:

\[ c \approx 7.38 \]

Thus, if you were to travel 4.5 miles, the corresponding dependent variable (the cost) would be approximately $7.38.
