Question

Write an algebraic expression To Represent the Pay in dollars For Working "x" hours at a rate of eight dollars and seventy-Five Cent per hour

Answer 1

`y=8.75x`

Explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
`y/x=k` or
`y=kx`

In this problem we have a proportional variation

Let

y ----> the pay in dollars

x ----> the number of hours worked

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin.

The slope or constant of proportionality in this problem is equal to

`k=\$8.75\ per\ hour`

substitute

The algebraic expression is equal to

`y=8.75x`
