Answer: 39$
Step-by-step explanation: 4 hrs and 30 mins and you make 27$
You gotta make the hrs into minutes. So you can find the rate. 4 hrs is 240 minutes. With the 30 minutes its a total of 270 minutes. You're earning 1 dollar every 10 minutes. So i think if i did the math right 390 minutes is 6 hrs and 30 mins. And so she has earned 39$.

just divide it by 3.2
Answer:
No
Step-by-step explanation:
In this particular scenario, based on the numbers I would say that it does not make sense to represent this with a constant rate. That is because in a span of three years the change between each year is completely different, for example, between the first and second year there was a change of
9.75 - 8.50 = 1.25 dollar change
1.25 / 8.50 = 0.147 or a 14.7% increase
Between the second and third year, there was a change of
12 - 9.75 = 2.25 dollar change
2.25 / 9.75 = 0.23 or 23% increase
Therefore, each year the percent and dollar value increase is increasing more and more which would not be a constant rate.
