Answer:
The total change in the amount of money in my account is $ 9.60
Step-by-step explanation:
Given:
Amount of money deposited each week, [tex]A_{d}=\$12.50[/tex]
Amount of money withdrawn each week, [tex]A_{w}=\$4.80[/tex]
∴ Amount of money deposited in 4 weeks, [tex]A_{dT}=A_{d}\times 4=12.50\times 4 = \$50[/tex]
∴ Amount of money withdrawn in 2 weeks, [tex]A_{wT}=A_{w}\times 4=4.80\times 2 = \$9.6[/tex]
Now, amount of money left in the account is the difference of the two amounts.
So, amount left = [tex]A_{dT}-A_{wT}=50-9.6=\$40.4[/tex]
Therefore, the total change in the amount of money in my account is given as:
Total change = Initial amount after 4 weeks - Final amount in the account.
Total change = $ 50 - $40.4 = $ 9.6
