always does 20 more sit ups than push-ups. Write an equation that represents this situation. \( \begin{array}{l}\text { (b) Explain what each part of the equation represents in } \\ \text { situation. }\end{array} \)

Let's represent the number of push-ups done as \( p \). Therefore, the number of sit-ups done can be represented as \( p + 20 \). The equation representing this situation is \( s = p + 20 \), where \( s \) is the number of sit-ups. In this equation, \( s \) denotes the total number of sit-ups performed, \( p \) indicates the number of push-ups completed, and the \( +20 \) signifies that the individual does exactly 20 more sit-ups than push-ups. This simple relationship highlights the individual's workout habit and helps in tracking their exercise routine efficiently!
