Question

Rosa is saving money for a trip. She has already saved 250$ and plans to save $40 per week. This situation can be represented by the function f(x)=250+40x, where x is the number of weeks. How much money has Rosa saved after 6 weeks?

Answer 1

Answer:

After 6 weeks Rosa has saved $490.

Step-by-step explanation:

1. You have the function given  in the problem above, where $x$ os the number of weeks:

$f(x)=250+40x$

2. Therefore, to solve this problem you only need to substitute 6 weeks (or $x=6$) into the given function, as following:

$f(x)=250+40x\\f(6)=250+40(6)=490$

3. The result is $490.
