Put the numbers that represents tacos, enchiladas and tamales in front of x, y and z
For instance,
2x+2y+1z=8.50
3x+2y+2z=13
1x+3y+2z=11.50
129.99
To do this you must multiply the price of all the steaks, then add the tax to that, then the tip.

Step-by-step explanation:
hope this helps
μ = 12; σ = 1.17
<span>z = ( 9 - μ ) / σ = -2.5641
</span>
<span>z = ( 15 - μ ) / σ = 2.5641
</span>
<span>P (9 < x < 15) = P (-2.5641 < z < 2.5641) = 0.9897 = 98.97%</span>
