-x+4=2x+1
4-1=2x+x
3=3x
x=1
y=-1+4
y=3
1.5 hours=90 minutes
Because 90 minutes/ 30 minutes is 3, multiply 3.6 miles by 3 and get 10.8 miles as your final answer
$10.71
Explanation
Step 1

Let
x represents the money Eileen will pay if her bag weighs 63 pounds

The effective annual interest rate is:
i = (1 + 0.064/12)^12 - 1 = 0.066
In year 1: the interest is $613.80 (multiple $9300 by 0.066)
In year 2: the interest is $654.31 (add interest from year 1 to $9300 and multiply by 0.066)
In year 3: the interest is $656.98 (do the same as year 2)
In year 4: the interest is $657.16
The total interest is: $2582.25
The present worth of this amount is:
P = 2582.23 / (1 + 0.066)^4 = $1999.72
The answer is $1999.72.
