Question

based on the information above, how many miles should a person who drives for 48 minutes expect to travel?
32 miles
42 miles
48 miles
54 miles

Explanation:

Step1: Substitute \(x = 48\) into the equation \(y = 1.04x-7.15\)

$$y=1.04\times48 - 7.15$$

Step2: Calculate \(1.04\times48\)

$$1.04\times48=(1 + 0.04)\times48=48+1.92 = 49.92$$

Step3: Calculate \(y\)

$$y=49.92-7.15=42.77\approx42$$

Answer:

42 miles
