Answer:
Let's solve the given questions using the provided function A(w) = 600 - 17w.
1. To find out how many weeks Dante has been saving when he still needs $294, we'll set A(w) equal to 294 and solve for w:
A(w) = 600 - 17w
294 = 600 - 17w
Now, solve for w:
17w = 600 - 294
17w = 306
w = 306 / 17
w ≈ 18
So, Dante has been saving for approximately 18 weeks.
2. To find out how much money Dante still needs after 5 weeks, we'll plug w = 5 into the function A(w):
A(w) = 600 - 17w
A(5) = 600 - 17 * 5
A(5) = 600 - 85
A(5) = 515
After 5 weeks of saving, Dante still needs $515 to buy the TV.
