The answer is, (1, -5)...
Answer:
checking account A is the better deal.
Step-by-step explanation:
A charges a monthly service fee = $12.00
Wire transfer fee = $10.50
B charges a monthly service fee = $21.00
Wire transfer fee = $8.50
If the requirement is four wire transfer per month
A charges for 4 wires = 10.50 × 4 = $42.00
and adding monthly service fees = 42.00 + 12.00 = $54.00
B charges for 4 wires = 8.50 × 4 = $34.00
and adding monthly service fees = 34.00 + 21.00 = $55.00
Therefore A charges less than B, so checking account A is the better deal.
Assuming that 1.5% annual interest is converted to monthly basis with the same amount, then the monthly interest should be: 1.5%/12= 0.125%.
If you put $1000 for annual interest, the saving account would become: $1000*(100%+1.5%)= $1015
If you put $1000 for monthly interest, the saving account would become: ($1000*(100%+0.125%)= $1000*1.0151035559= $1015.10
Then, the money difference should be: $1015.10-$1015= $0.10
Simplify the integrands by polynomial division.
Now computing the integrals is trivial.
