Delia is a graphic designer who charges an hourly rate. She made the graph to show her total earnings for various numbers of hou

stich3 [128]

Answer:

approximately 7 hours

see the explanation

Step-by-step explanation:

The picture of the question in the attached figure

Let

x ----> the time worked in hours

y ----> the amount earning in dollars

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem we have a proportional relationship

step 1

Find approximately how many hours would it take Delia to earn $250 ?

Looking at the graph

For y=$250 The value of x is approximately 7 hours

see the attached figure N 2

step 2

Find the exact value

from the graph take the point (5,175)

Find the value of k

$k=\frac{y}{x}$ ----> $k=\frac{175}{5}=\$35\ per\ hour$

The linear equation is

$y=35x$

For y=$250

substitute

$250=35x$

solve for x

$x=7.14\ hours$
