Final answer:
To have a daily pay over $100, Trevor will need at least 20 credit card applications.
Step-by-step explanation:
To determine how many credit card applications Trevor needs to get paid in order to have a daily pay over $100, we need to understand the payment charges related to late payments on credit cards. According to the given information, a credit card company charges $10 when a payment is late and $5 for each day the payment remains unpaid. Let's assume Trevor's daily pay is represented by 'x'. So, we can create an equation:
10 + 5(d-1) < x, where 'd' represents the number of days the payment remains unpaid. To find the number of credit card applications Trevor needs, we need to find the smallest positive integer value of 'd' that satisfies this equation. Suppose 'n' is the number of credit card applications.
Then, the equation becomes: 10 + 5(n-1) < 100. Solving this equation, we get n > 19. Therefore, Trevor will need at least 20 credit card applications to get paid and have a daily pay over $100.
