Answer:
$55.00
Step-by-step explanation:
$50.00 x .10 =$5.00
$50.00 + $5.00 =$55.00
D = distance
d^2 = x^2 + y^2
dd' = 2xx' + 2yy' Taking the derivative wrt time
d' = (2xx' + 2yy')/d
d' = (42x21 +56x28)/70 = 35 mph

Present age of Justin=14
Present age of Sam=11
<u>Step-by-step explanation:</u>
Let the present age of Sam=x
Given that Justin is 3 years older than Sam
present age of Justin=x+3
Age of Sam 3 years ago=x-3
Age of Justin two years hence=x+3+2=x+5
given that after 2 years Justin's age will be twice that of Sam's age three years ago
therefore
Present age of Sam=x=11
Present age of Justin=x+3=11+3=14
