The U.S- based motorcycle manufacturer says that it expects to build 146,000 motorcycles this year , up from 128,000 last year .

beks73 [17]

Answer:

14.06%

Step-by-step explanation:

Here we are asked to find the percent increase in the production of the motorcycle for US based manufacturer.

The production for the last year = 128,000

The production for the current year = 146,000

Total increased production = 146,000-128,000

= 18,000

Hence percentage calculation = $\frac{\ increase \ in \ sale}{\ last \ year \ sale} \times 100$ %

Increased percentage = $\frac{18000}{128000} \times 100$ %

= $0.140625 \times 100$ %

=14.06%
