b is the independent variable
Answer:
a) the beef cost the most
b) $125.8
Step-by-step explanation:
A) 1.2 potatoes
1.8 carrots
2.39 beef
.5 peppers
B) 15.30-.5=14.80 x 8.5=<u>125.8</u>
Equation 1 ==> y - x = -13
Equation 2 ==> -4x + 3y = -51
3(y - x) = 3(-13)
Equation 3 ==> 3y - 3x = -39
Equation 2 - 3
= (3y - 3y) + ( -4x - (-3x) ) = -51 - (-39)
-x = -12
x = 12
Substitude x into equation 1
y - 12 = -13
y = -1
