hammer [34]

Simple interest = Cost Price + (Interest Percentage of Cost Price × number of years or months we 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 × 3)
SI = £20 000 + (£1000 × 3)
SI = £20 000 + £3000 = £23 000

£24 000 - £23 000 = £1000 that you saved!

True or false: Two lines with undefined slopes are parallel to each other and parallel to the y axis

BlackZzzverrR [31]

Correct! lines that have undefined slopes are always parallel to the y-axis as the change in x is 0. A gradient is calculated by the change in y divided by the change in x and anything divided by 0 is referred to as undefined.

$\frac{y_{1}- y_{2} }{x_{1}- x_{2} }$

(calculation for a gradient)

Hope that helps sorry if its a bit confusing :)
