Answer:
the point where the graph crosses the y-axis.
Step-by-step explanation:
I took the quiz and this was the correct answer

where t is the number of hours worked by Natalle
Here, we want to write an equation that will represent the given scenario
Let the number of hours for which she earned the pay be t
From the question, she earns $11 per hour
So for t hours, the amount earned excluding the tip will be;

Now, let us add the tip and equate to the total amount earned
We have this as;
So paid160
75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost
I would round it to 81.1. If the .039 was 5 or over, I probably would have gone to 81.2.
Hope I helped! Have a nice day!
