Grace [21]

$x-\ cost\ of\ renting\ chair\\
y-\ cost\ of\ renting\ table\\\\
 \left \{ {{10x+2y=300\ \ \ \ \ \ \ \ \ \ \ \ } \atop {8x+4y=360\ \ \ | divide\ by\ -2}} \right. \\\\
 \left \{ {{10x+2y=300} \atop {-4x-2y=-180}} \right. \\\\+----\\addition\\\\\
6x=120\ \ \ | divide\ by\ 6\\\\
x=20\\\\
y=\frac{300-10x}{2}=150-5x=150-5*20=150-100=50\\\\
12x+3y=12*20+3*50=240+150=390\\\\

Option B

Step-by-step explanation:

First make x = 4 and y = 3 in the equation y = -1/2x + 5

it should look like 3 = -1/2(4) + 5 now we can solve

-1/2 * 4 = -2 → 3 = -2 +5

-2 + 5 = 3 → 3 = 3
