Answer 2

Answer:

It will take Katie 15 weeks to save up for her motor scooter.

Step-by-step explanation:

Step 1: Analyze Data

First, you can recognize that Katie is going to make $22 each week, making that our slope. She has already saved $188, so that is our y-intercept since it is our 'start amount.' And then we are given one more number, $518, which is our y value since it is our 'goal.'

Step 2: Create an equation

$518=188+22x$

Step 3: Solve for x

$518=188+22x\\330=22x\\x=15$
