Just to add onto this, vectors in economics are often column vectors by default. Thus it would be standard to write $p_i'x_i$ to denote the dot product of the two vectors representing total expenditures.

<p>So what does a vector mean in economics, in layman's terms?
For example,
<a href="https://en.wikipedia.org/wiki/Hicksian_demand_function" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/Hicksian_demand_function</a></p>
<blockquote>
<p>where <span class="math-container">$h(p,\bar{u})$</span> is the Hicksian demand function, or commodity bundle demanded, at price vector p and utility level
<span class="math-container">$\bar{u}$</span>. Here p is a vector of prices, and x is a vector of quantities demanded, so the sum of all <span class="math-container">$p_ix_i$</span> is total expenditure on all goods.</p>

<p>Is a price vector here just a bundle of prices <span class="math-container">$(p_1, p_2, ..., p_n)$</span> that verifies vector space properties?</p>

> $\bar{u}$. Here p is a vector of prices, and x is a vector of quantities demanded, so the sum of all $p\_ix\_i$ is total expenditure on all goods.

Is a price vector here just a bundle of prices $(p\_1, p\_2, ..., p\_n)$ that verifies vector space properties?

The meaning is same as in mathematics.

Indeed price vector $\mathbf{p}$ is just:

$$\mathbf{p} = (p\_1,p\_2, ... , p\_n)$$
