Plug in 300 for C(x), to get:
300=

Then subtract to get: 0=

Then use the quadratic formula and plug everything in. Use a calculator to simplify.
You'll get two answers: 29.486 and -0.513.
Since you can't sell <em>"negative" </em>tacos, use the positive solution
Around 29-30 tacos.
X+y=12 -- 1
3x+2y=29 -- 2
(1)x2
2x+2y=24 -- 1
(2)-(1)
x=5
Sub x into 1
x+y=12
5+y=12
y=7

Answer:
4x>74+9
Step-by-step explanation:
4x+2×45
2×45x
74x×2
4x>9
4x>74+9
X = 8
because 8 x 2 = 16
16 - 9 = 5
5 x 3 = 15
I think you would multiply 4 and 10 and that equals 40.
