Raya buys a van for £8500 plus vat at 20%
raya pays a deposit for the van.
she then pays the rest of the cost in 12 equal payments of £531.25 each month
find the ratio of the deposit raya pays to the total of the 12 equal payments.
give your answer in its simplest form.

They buy the van for £8,500 + VAT 20%:

Total paid for the van = £8,500 x 1.20 = £10,200

They make 12 payments of £531.25 for a total of:

12 x £531.25 = £6,375

To find the amount of deposit, subtract the total payments from total cost:

£10,200 - £6,375 = £3,825

The ratio of deposit to the payments is: 3825 : 6375

Reduce the answer by dividing both numbers by 75:

3825/75 = 51

6375 / 75 = 85

The ratio becomes: 51/85

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

12
