1) reflection across the y-axis 스
A) W(-4,1), x(-3, 2), V(-5,3)
B) V(-2,-5), w(-1, -3), x(0, -4)
C) V(2, -1), w(3, 1), x(4,0)
D) W(4, -1), 2(3, -2), V(5. -3)

The solution in each item is enumerated below:

For item#1,
Interest in a year = savings amount * interest rate * time
Interest in a year = $55,000 * 2% * 1 year
Interest in a year = $1,100

For item#2,
Amount to keep inflation = $55,000 * 3.24% * 1 year
Amount to keep inflation = $ 1,782

For item#3,
Buying power loss = $1,782 - $1,100
Buying power loss = $682
