Answer :

Final answer:

Jennifer weighs 99 pounds which is 5 pounds less than two thirds of her father's weight. Set up and solve this algebra problem to conclude that Jennifer's father weighs 156 pounds.

Explanation:

The subject of this question is Mathematics, specifically an area of study involving basic algebra. In order to solve this problem, one must set up an equation to represent the given information, and then solve for the unknown variable. From the problem, we know that Jennifer's weight (99 lbs) is 5 pounds less than two thirds of her father's weight. This can be represented by the equation: 99 = 2/3 * Father's weight - 5.

To solve for Father's weight, the first step is to add 5 to both sides of the equation, resulting in 104 = 2/3 * Father's weight. The final step is to multiply each side by the reciprocal of 2/3, which is 3/2, to isolate the Father's weight. This results in Father's weight = 104 * 3/2 = 156 pounds. Therefore, Jennifer's father weighs 156 pounds.
