Answer 2

15.5 weeks of school lunch would cost $550.25

Explanation:

The unit rate is already given here, so all you need to do here is multiply the cost per week by the number of weeks. You can even think of it as canceling out the weeks:

`(cost)/(week)* week=cost`

`35.50*15.5=550.25`

15.5 weeks of school lunch would cost $550.25

You could also write this as a linear equation with a slope of 35.5 and a y-intercept of 0:

`y=35.50x`
