The answer should be C. By combining like terms you can find the answer. 1.75a+2.75a = 4.5a
2.25b + 1.75b = 4b
2.25c + 1.25c = 3.5c

$1.6

Step-by-step explanation:

We need to find the cost of 80 cm of copper pipe at $2 a metre.

Cost of 1 metre = $2

80 cm = 0.8 m

It means,

0.8 m = $2 × 0.8

= $1.6

So, the cost of 80 cm of copper pipe is equal to $1.6.
