Give your answer in dollars, correct to the nearest cent. Answer $ ...

1. Calculate the amount paid into the pension.

Pension payment:

$8\% \text{ of } 5625 = \frac{8}{100}\times 5625 = 450$

So Jenny pays $450 into her pension.

2. Find the remainder after the pension payment.

Remainder after pension:

$5625 - 450 = 5175$

3. Calculate 5% of the remainder and subtract it.

Savings payment:

$5\% \text{ of } 5175 = \frac{5}{100}\times 5175 = 258.75$

Amount left:

$5175 - 258.75 = 4916.25$

1. Calculate the deposit paid.

Deposit $= \dfrac{1}{5} \times 900 = 180$

2. Calculate the total paid including the monthly payments.

Total monthly payments $= 12 \times 64 = 768$

Total amount paid $= 180 + 768 = 948$

1. Represent the current rent as a percentage of last year's rent.

Since $2064 is $7.5\%$ more than last year's rent,

$\text{current rent} = 100\% + 7.5\% = 107.5\%\text{ of last year's rent}.$

2. Calculate last year's monthly rent.

$\text{last year's rent} = 2064 \div 1.075$

$= 1920$

1. Convert €230 to Singapore dollars.

Since $1 = €0.65,

$€230 = \$\left(230 \div 0.65\right)$

$= \$353.8461538\ldots$

2. Add the 1.6% currency conversion fee.

Total amount including the fee

$= 353.8461538\ldots \times 101.6\%$

$= 353.8461538\ldots \times 1.016$

$= 359.5076923\ldots$

3. Round the total bill to the nearest cent.

$359.5076923\ldots \approx 359.51$

So the total amount on Jenny’s credit card bill is $359.51.
