Answer:
$673.27
Step-by-step explanation:
Initial amount = $660
1% Increase = $660*(1+1%)
1% Increase = $660+$6.6
1% Increase = $666.6
Further 1% Increase = $666.6*(1+1%)
Further 1% Increase = $666.6 + $6.666
Further 1% Increase = $673.266
Further 1% Increase = $673.27
Answer:
Step-by-step explanation:
Answer:
Boat = 20 mph
Current = 5 mph
Step-by-step explanation:
If b is the speed of the boat, and c is the speed of the current, then:
b + c = 225 / 9 = 25
b − c = 225 / 15 = 15
Solve the system of equations with elimination.
2b = 40
b = 20
Plug back into either equation to find the speed of the current.
c = 5
The second choice! I hope my math is right!
