Answer:
C i think
Step-by-step explanation:
If u were to add 5x+20=9x you’d get x=5
To answer the question, let x be the cost of each hamburger, y be the cost of each medium fries, and z be the cost of each medium drink. The equations that are described in the problem are,
(Miller ) 4x + 3y = 18.69
(James) x + 2y + z = 8.66
(Steven) 2x + y + z = 10.27
Solving simultaneously for the values of the variables give x = 3.36, y = 1.75, and z = 1.8.
Thus, each hamburger costs $3.36. Each medium fries cost $1.75, and each drink costs $1.8.
Answer: Yes, it is correct
Step-by-step explanation: Because of that, When you multiply 4.2 x 3 x 4 = 50.4
