Answer:
1539
Step-by-step explanation:
We solve the above question using the Exponential decay formula
= A(t) = Ao(1 - r) ^t
Ao = Initial Amount invested = 7600
r = Decay rate = 55% = 0.54
t = time in weeks = 2
Hence:
A(t) = 7600(1 - 0.55)²
A(t) = 7600 × (0.45)²
A(t) = 1539
Therefore, the value of the quantity after 2 weeks is 1539
Total amount needed for the video game = $200
Total amount of money saved = $68
Amount of money that is needed to be saved = 200-68 =132
So raj needs to work additional hours in order to earn the remaineder$132 for the video game
Hourly wage = $5.5
So, number of hours that Raj needs to work to earn $132 = $132/5.5 = 24 hours
Number of hours that Raj needs to work to earn the remainder of the money = 24 hours
I think the answer would be the first one
