Question

Zachary works on a small commercial fishing boat that is 120 feet long. Foster works on a boat that is 80% longer than the boat that Zachary works on. How long is the boat that Foster works on?

A. 216 feet
B. 150 feet
C. 132 feet
D. 96 feet

Answer 1

Calculating 80% of the 120-foot-long boat gives 96 feet. Adding this to the original length results in Foster's boat being 216 feet long.

Step-by-step explanation:

To find out how long the boat that Foster works on is, we need to calculate 80% of Zachary's boat length and add it to the original length. Zachary's boat is 120 feet long. To find 80% of this, we convert 80% to a decimal (80/100 = 0.8) and multiply by the length of Zachary's boat:

80% of 120 feet = 0.8 × 120 feet = 96 feet.

Now we add this to the original length of Zachary's boat to find Foster's boat length:

Zachary's boat + additional length = 120 feet + 96 feet = 216 feet.

So, the boat that Foster works on is 216 feet long, which corresponds to option A.
