15.95a + 22.95b = 2779.....multiply by -1
15.95a + 17.90b = 2385.10 (I got the 17.90 by taking 22% off of 22.95)
------------------------------
-15.95a - 22.95b = - 2779 (result of multiplying by -1)
15.95a + 17.90b = 2385
------------------------------add
- 5.05b = - 394
b = -394 / -5.05
b = 78
15.95a + 22.95b = 2779
15.95a + 22.95(78) = 2779
15.95a + 1790.10 = 2779
15.95a = 2779 - 1790.10
15.95a = 988.90
a = 988.90 / 15.95
a = 62
style A sold was 62
style B sold was 78
Answer:
Amount Blaine save = $250
Step-by-step explanation:
Total take home pay = $2,500
Original budget:
Rent + electricity bills = $990
Food/groceries = $525
Gas + insurance = $320
Spending money = $235
Cellphone + Internet = $250
Gym membership = $180
Total = $2,500
New budget:
Rent + electricity bills = $990
Food/groceries = $525
Gas + insurance = $320
Spending money = $200
Cellphone + Internet = $175
Gym membership = $40
Total = $2,250
How much will these choices save him each month?
Amount Blaine save = Total take home - new budget
= $2,500 - $2,250
= $250
Amount Blaine save = $250

Answer: y = -2x - 7
Step-by-step explanation:
The equation for a perpenducular line has a slope that is the negative inverse of the reference line, in this case x - 2y = 6.
Let's put this equation into standard slope-intercept form, y = mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).
x - 2y = 6
- 2y = 6 - x
y = (1/2) x -3
The slope is (1/2), so a perpendicular line will have a slope of -2.
y = -2x + b
We can find b by using the given point ((-3,-1), a known solution):
-1 = -2*(-3) + b
-1 = 6 + b
b = -7
The perpendicular equation is y = -2x - 7
y = -2x
