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 nember of weeks. how much money has rosa saved after 6 weeks?

Respuesta :

Rosa has saved $490 in 6 weeks.

To find the answer to this, simply plug the number of weeks in for the value of x and solve.

f(x) = 250 + 40x

f(6) = 250 + 40(6)

f(6) = 250 + 240

f(6) = 490
