Well i think the answer is
Brand X cost: $4.50
Brand Y cost: $3.50
Christopher spends total: $49.50
Equation: 4.50x + 3.50y = 49.50
Idk how to solve the equation but this should be the correct equation
Answer:
The answer to your question is in the picture below
Step-by-step explanation:
y + 3/4x < 2
y+ 3/4x = 2
y = -3/4x +2
Interceptions (0,2) and (8/3, 0) It's a dotted line and we are interested in the area below the line
y - 1 ≥ 2x
y - 1 = 2x
y = 2x + 1 Interception, it's not a dotted line with interceptions (0,1) and (-1/2, 0), we are interested in the area up the line.
Is there an image you can provide if possible
