The expression that can be used to find profit is 20x – 50 and that profit when 75 pairs of jeans are sold is 1,450.
<h3>How find profit function and the profit?</h3>
Let R represents the revenue function and C represents the cost function, the two functions can be stated correctly as follows:
R = 2x^2+17x−175
C = 2x^2−3x−125
Let P represents the expression that can be used to find profit, we therefore have:
P = R – C
P = 2x^2+17x−175 – (2x^2−3x−125)
P = 2x^2+17x−175 – 2x^2 + 3x + 125
P = 2x^2 – 2x^2 + 17x + 3x – 175 + 125
P = 20x – 50
The profit when 75 pairs of jeans are sold can therefore be calculated as follows:
P = (20 * 75) – 50
P = 1,450

Step-by-step explanation:
Divide
Answer:
<em>Henson: 3x + y = 163</em>
<em>Garcia: 2x + 3y = 174</em>
<em>adult ticket price: $45</em>
<em>child ticket price: $28</em>
Step-by-step explanation:
Henson Family:
3 adults + 1 child; total $163
3x + y = 163
Garcia Family:
2 adults + 3 children; total $174
2x + 3y = 174
Now we solve the system of equations.
Solve the first equation (Henson Family) for y.
y = 163 - 3x
Substitute 163 - 3x for y in the second equation (Garcia Family).
2x + 3<em>y</em> = 174
2x + 3(<em>163 - 3x</em>) = 174
2x + 489 - 9x = 174
-7x + 489 = 174
-7x = -315
x = 45
Now substitute 45 for x in the first original equation and solve for y.
3x + y = 163
3(45) + y = 163
135 + y = 163
y = 28
adult ticket price: $45
child ticket price: $28
Answer:
40 miles a day
Step-by-step explanation:
The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:
A: 90 + 0.30·40 = 102
B: 70 + 0.80·40 = 102
5.6 is the correct answer because 1.3 +4.3 would be 5.6 so the next one in the sequence is 9.9
