Question 1 • 2025-2026 FBISD - Precalculus B (CR)

Brenda already has $200 to put toward the purchase of a new laptop that sells for $450. She will save $50 each month, starting next month, until she can buy the laptop. Which of the following represents the amounts she will have each month, starting next month, until she can afford to buy the laptop (assuming there is no sales tax)?

Answer
A
$200, $250, $300, $350, $400, $450
B
$250, $300, $350, $400, $450
C
$0, $200, $250, $300, $350, $400, $450
D
$50, $200, $450

Explanation

Brenda starts with $200 and adds $50 each month, beginning next month. Her amounts will be $250, $300, $350, $400, and then $450, when she can afford the laptop. Choice B lists those monthly amounts; choice A incorrectly includes her starting amount before next month.
