Question

The table below shows Aria's earnings on the job.

Time (hours) Time (hours) Earnings (dollars) Earnings (dollars)
1818
2323
2929
$451.80$451.80
$577.30$577.30
$727.90$727.90
What is the constant of proportionality between
earnings and time in hours?
Please help me.

Answer 1

To find the constant of proportionality between earnings and time in hours, we can use the formula:

Constant of proportionality = Earnings / Time

Using the given data:

Earnings (dollars): $451.80, $577.30, $727.90
Time (hours): 18, 23, 29

Let's calculate the constant of proportionality for each pair of earnings and time:

For the first pair:
Constant of proportionality = $451.80 / 18 = $25.10

For the second pair:
Constant of proportionality = $577.30 / 23 = $25.10

For the third pair:
Constant of proportionality = $727.90 / 29 = $25.10

We observe that the constant of proportionality between earnings and time in hours is the same for all the data points, which is $25.10.

Therefore, the constant of proportionality between earnings and time in hours is $25.10.
