Answer:
Decrease in dollars is $555.00, $6845.00 was in his account at the end of last year.
Step-by-step explanation:
7400 times 7.5/100
=74 times 7.5
=$555.00
7400-555=$6845.00
Given:
Original or base : 40
New amount : 72
We need to find the difference of the new amount and the original amount
72 - 40 = 32
We then divide the difference by the original amount
32/40 = 0.80
We multiply the quotient by 100%
0.80 x 100% = 80%
The percentage of change is 80%
