Kate is saving to take an SAT prep course that costs $350. So far, she has saved $180 and can save $17 each week. Write and solve an equation to determine how many more weeks she must save to be able to
afford the course.

10 weeks.

Step-by-step explanation:

Let 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:

Let's solve:

Subtract from both sides of the equation.

Divide both sides of the equation by the coefficient of , which is :

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
