Answer:

Assuming you mean from $60 to $45, that would be 25%.

Step-by-step explanation:

We can use the simple formula: $\frac{NEW-OLD}{OLD} *100$

In this case: $\frac{45-60}{60} *100 = -25$

Which means there is a 25% discount.

75 - 3.5x - 4x = 4x + 6

stepladder [879]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

75 - 3.5x - 4x = 4x + 6

Step 2: Solve for x

Combine like terms: 75 - 7.5x = 4x + 6
Add 7.5x on both sides: 75 = 11.5x + 6
Subtract 6 on both sides: 69 = 11.5x
Divide both sides by 11.5: 6 = x
Rewrite x = 6

Step 3: Check

Plug in x to verify it's a solution.

75 - 3.5(6) - 4(6) = 4(6) + 6

75 - 21 - 24 = 24 + 6

54 - 24 = 30

30 = 30
