Multiply 1050 by 14 and add to 1280 x 17 and divide by total days:
((1050 x 14) + (1280x17)) / ( 14+ 17)
You would then need to calculate the interests for that time period by dividing the annual interest rate by days in a year and multiply by total days in the billing cycle:
0.19/365 x 31
The finale Aquarian would be:
(0.19/365 x 31) ((1050 x 14) + (1280x17)) / ( 14+ 17)
I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
