Question

Juan is saving money for a new car. He has already saved $200 and plans to save $25 per week. This situation can be represented by the function f(x) = 200 + 25x, where x is the number of weeks. How much money has Juan saved after 8 weeks?

$200
$400
$600
$800

Answer 1

400 is the correct answer. I am too lazy to put an explanation, but trust me it's not 800, I just got it wrong.

Answer 2

He would have $400 after 8 weeks.
