Answer:
5. ST 6. AT
Step-by-step explanation:
For a product to be divisible by a number, one of the factors must be that number. This can be achieved by one of the consecutive numbers being that number, or a multiple of that number.
5. 4 x 5 x 6 = 120 which is divisible by 5
1 x 2 x 3 = 6 which is not divisible by 5
6. 1 x 2 x 3 = 6 which is divisible by 6
2 x 3 x 4 = 24 which is divisible by 6
3 x 4 x 5 = 60 which is divisible by 6
4 x 5 x 6 = 120 which is divisible by 6
And now we will just repeat ourselves.
The original price is $199.94
Given:
Discounted price = 159.95
Discount rate = 20%
If the discount rate is 20%, then the price is equivalent to 80%.
To get the original price, simply divide the discount price by its corresponding percentage.
Original price = 159.95 ÷ 80% = 199.94
To check
199.94 * 20% = 39.99 * value of the discount
199.94 - 39.99 = 159.95 *discounted price
Y-585 = -7.5(x-15)
y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50
C = -7.5(52) + 697.50 = $307.50
