-8 ÷ 2 = -4
As one formula you can write this as:
∴ The midpoint is -4.
Simple Interest = Cost Price + (Interest Percentage of Cost Price × number of years or months you are paying off)
a) SI = $20 000 + (5% of $20 000 × 4)
SI = $20 000 + ($1000 × 4)
SI = $20 000 + $4000 = $24 000
b) SI = $20 000 + (5% of $20 000 × 2)
SI = $20 000 + ($1000 × 2)
SI = $20 000 + $2000 = $22 000
<span>$24 000 - $22 000 = $2000 that you save!</span>
