Sorry for the delay!
Let x = charge before tax in 1st city, and y = charge before tax in 2nd city
y = $1500 + x
4/100x => tax in first city
3.5/100y => tax in second city
0.04x + 0.035y = $408.75
We have the following system of equations to solve:
So the hotel charge before tax in city 1 = $4750, and the hotel charge before tax in city 2 = $6250

Answer:
[8, 44]
Step-by-step explanation:
The average of equally-weighted values is their sum divided by their number.
<h3>Setup</h3>
For some fourth test score x, Paul wants an average between 70 and 79. This gives rise to the inequality ...
70 ≤ (91 +88 +93 +x)/4 ≤ 79
<h3>Solution</h3>
Multiplying by 4, we have ...
280 ≤ 272 +x ≤ 316
8 ≤ x ≤ 44 . . . . . . . . . . subtract 272
Paul will get a C if his fourth test score is in the interval [8, 44].
