Answer: altitude at starting point is -11ft or 11ft below sea level
Step-by-step explanation:
Equation for this situation will be
A = Ag - 11
A = actual altitude
Ag = altitude gained.
At starting point, altitude gained is zero, therefore;
A = 0 - 11
A = -11ft
$168 - (8 times $5)=
$168 - $40 =
$128 = 8 trees
1 tree = $128 divided by 8=
1 tree = $16
