Option B) 60 is half the sum of a number and 40.

Option D) A store has a sale in which all items are 50% off. At the store, Tony spends a total of $60 for a jacket that costs x dollars and a pair of pants that costs $40.

Step-by-step explanation:

we have the equation

$\frac{1}{2}(x+40)=60$

Verify each case

case A) 40 more than 50% of a number is 60.

Let

x -----> the number

The situation is

$\frac{1}{2}x+40=60$

therefore

The situation cannot be represented with the given equation

case B) 60 is half the sum of a number and 40

Let

x -----> the number

The situation is

$60=\frac{1}{2}(x+40)$

Rewrite

$\frac{1}{2}(x+40)=60$

therefore

The situation can be represented with the given equation

case C) A test is worth 100 points. Each question, x, is worth 1/2 a point

Let

x -----> the number of questions

The situation is

$\frac{1}{2}(x)=100$

therefore

The situation cannot be represented with the given equation

case D) A store has a sale in which all items are 50% off. At the store, Tony spends a total of $60 for a jacket that costs x dollars and a pair of pants that costs $40.

Let

x -----> the cost of a jacket

The situation is

$\frac{1}{2}(x+40)=60$

therefore

The situation can be represented with the given equation
