Answer:
150 miles
Step-by-step explanation:
Find the unit rate (MPH) by dividing miles travlled by hours.
300/6 = 50 MPH
250/5 = 50 MPH
Multiply the hours on day 3 (3) by 50 MPH
3*50 = 150 miles
$42,500 because 45900 dividede by 1.08 is 42500
The first step can be subtracting 2x from both sides leaving the equation with 6x + 3 = -15
