Answer 1

Week 4

Explanation:

Victoria has $250 and saves $150 each week, hence have increments $150 each week

250+150 (first week)

= 400

second week = 400 + 150 = 550

third week = 550 + 150 = 700

fourth week = 700 + 150 = $850

Felicia on the other hand has $1,650 and spends $200 each week, hence has decrements of $200 each week.

1650+200 (first week)

= 1450

second week = 1450 - 200 = 1250

third week = 1250 - 200 = 1050

fourth week = 1050 + 200 = $850
