3 kilometres = 3,000 metres
so the ratio is 500 : 3000
= 1 : 3000/500
= 1: 6

Answer:
The function is y = 17000 + 820 x
where: y = price of the car.
x = time in years.
After 3.3 years, the car will cost $19706.
Step-by-step explanation:
Hi there!
Let y be the price of the car.
After the first year, the price of the car will be:
y = 17000 + 820
After the second year:
y = 17000 + 820 + 820 or 17000 + 820(2)
After the third year:
y = 17000 + 820 + 820 + 820 or 17000 + 820(3)
Then, after x years:
y = 17000 + 820 x
After 3.3 year, the car will cost:
y = 17000 + 820(3.3) = 19706
After 3.3 years, the car will cost $19706.
Answer:
$122.50
Step-by-step explanation:
Sale Price: $70
Percent off: 75%
First, find 75% of 70.
To do so, you must change the percent to a decimal (75% to .75) and multiply it by 70.
.75 x 70 = 52.5
52.5 is the amount of money that was taken off the original price, so in order to find that, you must add it to the sale price.
52.5 + 70 = 122.5
So the original price was $122.50
