Question

Two pieces of equipment were purchased for a total of 2,000. If one piece cost $770 more than the other, find the price of the less expensive piece of equipment. Assume all data are accurate to two significant digits unless greater accuracy is given.

Answer 1

Given:

The cost price of two pieces of equipment was $2000.

The cost price of one is $770 more than the other.

To find the price of the less expensive piece of equipment:

Let x be the price of the less expensive piece of equipment.

That is, x+770 is the price of the other piece of equipment.

So, we write it as,

`\begin{gathered} x+x+770=2000 \\ 2x=1330 \\ x=665 \end{gathered}`

So, the price of the less expensive piece of equipment is $665.
