X = # of posters, y = total cost
y = 2x + 250
y = 1000

1000 = 2x + 250
1000 - 250 = 2x
750 = 2x
750/2 = x
375 = x....so 375 posters can be printed
==========================
y = total cost, x = # of miles

y = 3x + 3
y = 117

117 = 3x + 3
117 - 3 = 3x
114 = 3x
114/3 = x
38 = x.....so the car was towed 38 miles

Replace the CIRCLES by A and the SQUARES by B:

1) A + B = 14 And

2) A - B = 2

Add 1) + 2)

A+B =14
A-B = 2
------ ----
2A+0 = 16 then A = 16/2 = 8. If A = 8, then B = 6

So the CIRCLE = 8 and the SQUARE = 6

Answer:

8696.10

Step-by-step explanation:

If a car depreciates by 7% each year, this means that 7% of its value that year is subtracted from its previous value. In other words, you can multiply its value by (1-0.07)=0.93.

$12500\cdot 0.93^5\approx 8696.10$ . Hope this helps!
