How did you compute the cost of 4 pounds of beef at $5.89 per pound? Use this example to explain your strategy.

$23.56

Step-by-step explanation:

Step one:

given data

We are told that the unit cost per pound is $5.89

Required

the cost of 4 pounds

If 1 pound cost $5.89

4 pounds  cost x

cross multiply

x= 4*5.89

x=$23.56

its a straight line parallel to the time axis

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
