Answer:
The expression for the combine total dollar amount she earned this month is -t +957
Step-by-step explanation:
Let t be the number of hours she worked as a tutor.
The number of hours she worked as a waitress= 87-t
Then according to the given statement, the equation will be:
Amount she earned = 10t+11(87-t)
Now solve the expression:
=10t+957-11t
= -t +957
The expression for the combine total dollar amount she earned this month is -t +957....

Step-by-step explanation:
Using the velocity formula, it is found that the acceleration is of a = 9.8 m/s².
<h3>What is the velocity formula?</h3>
It is given by the initial velocity plus acceleration multiplied by time, that is:
v(t) = v0 + at.
In this problem, we have that v(0) = 0, t = 2, v(2) = 19.6, hence:
v(t) = v0 + at.
19.6 = 0 + 2a.
2a = 19.6.
a = 19.6/2.
a = 9.8 m/s².
The acceleration is of a = 9.8 m/s².
