Answer :

Given:

Amount he earns per hour = $17

Cost of new shirt = $25

Amount left = $825

Let's find the number of hours Stephen worked this week.

Let's first write a linear equation representing this situation.

Apply the slope-intercept form:

y = mx + b

Thus, we have the equation:

825 = 17h - 25

Now, let's solve for h.

Add 25 to both sides of the equation:

825 + 25 = 17h - 25 + 25

850 = 17h

Divide both sides by 17:

[tex]\begin{gathered} \frac{850}{17}=\frac{17h}{17} \\ \\ 50=h \\ \\ h=50 \end{gathered}[/tex]

Therefore, Stephen worked 50 hours this week.

ANSWER:

• Equation:

17h - 25 = 825

• Number of hours worked:

50 hours
