21 because you just multiply the 2 numbers.
To find your new number of sales per month, you will need to find the number of sales you have per month (based on 30 days per month).
55 x 20 = 1650 sales.
Than, you will need to calculate what 10% of this is and add it to your original sales number.
0.1 (10%) x 1650 = 165
1650 + 165 = 1815
You will need approximately 1815 sales based on the 30 day month.
Answer: 3a = (0, 1) 3b = (2, 1) 3c = (2.5, 1) 3d = (1.6, 1)
4a = (2, 3.5) 4b = (2, 3) 4c = (2, 5.375)
<u>Step-by-step explanation:</u>
The length of AB is 6 and is horizontal (affects the x-coordinate)


***********************************************************************************
The length of AB is 5 and is vertical (affects the y-coordinate)

-6 is the slope
Hope this helps
