Answer:

7.9% reduction.

Step-by-step explanation:

Kerrin's initial weight can be calculated by 13(14)+7=189 pounds.

Three months later he weighs 12(14)+6=174 pounds.

The difference between 189 and 174 is 15 pounds.

$\frac{15}{189}$ ≈.0793651 or 7.9%.

Answer:

Step-by-step explanation:

Let volume of container = x

1/6x + 5 = 1/2x

x/6 + 5 = x/2

Multiply through by 6

x + 30 = 3x

Subtract 30 from both sides

x + 30 - 30 = 3x - 30

x = 3x - 30

x - 3x = - 30

-2x = - 30

x = 30 /2

x = 15
