Final answer:
DJ Pots and Pans' rate is represented by the function d(j) = 150 + 101j. Ms. Berry can afford to hire the DJ for 1 hour with her $350 budget. For a 5-hour wedding, she would spend a total of $655.
Step-by-step explanation:
To represent DJ Pots and Pans' rate with a function, we need to take into account the fixed cost of showing up and the hourly rate. The function d(j) where j represents the number of hours the DJ plays is:
d(j) = 150 + 101j
For part b, if Ms. Berry has $350 to spend, we can calculate the maximum number of hours she can afford as follows:
350 = 150 + 101j
j = (350 - 150) / 101
j ≈ 1.98 ≈ 1 hour (since she can't hire the DJ for a fraction of an hour)
So, Ms. Berry can afford to hire DJ Pots and Pans for 1 hour.
For part c, the wedding runs for 5 hours (from 7 p.m. to 12 a.m.), thus:
Cost = 150 + (101 × 5)
Cost = 150 + 505
Cost = $655
Therefore, Ms. Berry will spend $655 to rent DJ Pots and Pans for her 5-hour wedding.
