Question

1. copper wire sells for $0.74 per meter. how much does a piece of copper wire 4.50×10^4 cm long cost? $1,330.00 $1.73 $133.00 $33.30 clear all

Explanation:

Step1: Convert length to meters

Since 1 m = 100 cm, then $4.50\times10^{4}$ cm $=\frac{4.50\times 10^{4}}{100}=450$ m.

Step2: Calculate the cost

The cost per meter is $0.74$. So the cost of a 450 - m wire is $0.74\times450 = 333$.

Answer:

$333.00$
