Final answer:
The total cost for a $10 shirt and n pairs of shoes at $15 each is expressed as C = $10 + 15n.
Step-by-step explanation:
To represent the situation of the total cost of buying a shirt and multiple pairs of shoes, we will use an algebraic expression. The shirt costs a fixed amount of $10. Since the number of pairs of shoes is variable and represented by n, and each pair of shoes costs $15, the cost of the shoes will be expressed as 15n, where n indicates the number of pairs.
Therefore, the total cost C can be found by adding the fixed shirt cost to the variable cost of the shoes: Total Cost Expression:C = $10 + 15n.This expression allows for calculating the total cost C for any number of pairs of shoes n purchased.
