Answer:
Step-by-step explanation:
The sale price = Initial Cost - 15% of the initial Cost
The sale price = 1250 - 15/100 * 1250
The sale price = 1250 - 187.5
The Sale Price = 1062.5
Now you add on the sales tax
Cost with Sales Tax = 1062.50 + 6.5/100 * 1063
Cost with Sales Tax = 1062.50 + 69.06
Cost with Sales Tax = 1131.56 dollars.
This would be the identity property of addition telling us that any number added to zero is that number (i.e. 6 added to zero is still 6)
When multiplying two numbers, a person can mentally add one of those numbers the other number amount of times.
The line of best fit would be y = x + 490
