The amount of money that sarah earns varies directly with the number of hours worked. If sarah earns $320 for working 40 hours, determine the constant of proportionality. (1 point)

Answer 1

To determine the constant of proportionality, we can set up a proportion using the given information:

$320/40 = x/1

Simplifying the left side:

$8 = x/1

Simplifying the right side:

x = $8

Therefore, the constant of proportionality is $8.
