So 50 per week+3 times number of sales
represent s as number of sales
pay=50+3s
if you want pay to be at least 110 or pay<u><</u>110 so
110<u>></u>pay=50+3s
110<u>></u>50+3s
treat as regular equation: do the saem to both sides so it will stay equal
also isolate the s term
110<u>></u>50+3s
subtract 50 from both sides
60<u>></u>3s
divide both sides by 3
20<u>></u>s
you must make at least 20 sales

Answer:
(7)(7)(1)=49 mm^3
Step-by-step explanation:
Answer: The "independent variable" is the "time" (in hours) that is plotted on the "x-axis". Note the "time" (in hours) can be "manipulated" in the sense that is it "chosen" by the humans who are measuring the data (e.g. when to start, how many hours, and at what intervals.
The "dependent variable" is the measurement (in feet) above or below the sea level, and this is plotted on the "y-axis". These values cannot be "manipulated" in the sense that one cannot "choose" what value or measurement the tide level would be at any particular time.
Hope these answers—and explanations—are of help to you.
Best wishes!
