Answer:

10 weeks.

Step-by-step explanation:

Let [tex]w[/tex] equal the number of weeks.

Let's construct a linear equation that equals the total cost of the SAT prep course, demonstrates Kate has already saved $180, and represents $17 saved per week:

[tex]350=17w+180[/tex]

Let's solve:

[tex]350=17w+180[/tex]

Subtract [tex]180[/tex] from both sides of the equation.

[tex]170=17w[/tex]

Divide both sides of the equation by the coefficient of [tex]w[/tex], which is [tex]17[/tex]:

[tex]w=10[/tex]
