4-97. Use absolute value to write an expression describing the size of each amount. An elevation of 250 feet. a. A credit card balance of \( \$ 23.75 \). b. A football player rushed for -5 yards. c. A bank balance of \( \$ 198.32 \). d. An elevation of Death Valley of -86 m .

To express the size of each amount using absolute value, we want to eliminate any negative signs, focusing solely on how much they represent. For the examples given: a. The absolute value of the credit card balance is represented as \( | -23.75 | = 23.75 \). b. For the football player's rush, the absolute value becomes \( | -5 | = 5 \) yards. c. The bank balance's size is expressed as \( | -198.32 | = 198.32 \). d. The elevation of Death Valley translates to \( | -86 | = 86 \) meters. These transformations show how absolute value captures the concept of "size" regardless of direction!
