Explanation:
Toby's loan amount is $450 and the finance charge is $50 every two weeks. He rolls over the loan 4 times.
Total cost = $450 + ($50 x (1 + 4))
Total cost = $450 + ($50 x 5)
Total cost = $450 + $250
Total cost = $700
Therefore, the total cost of Toby's payday loan is $700.
Tabitha's loan amount is $300 and the finance charge is $40 every two weeks. She rolls over the loan 6 times.
Total cost = $300 + ($40 x (1 + 6))
Total cost = $300 + ($40 x 7)
Total cost = $300 + $280
Total cost = $580
Therefore, the total cost of Tabitha's payday loan is $580.
Sariah's loan amount is $500 and the finance charge is $45 every two weeks. She rolls over the loan 7 times.
Total cost = $500 + ($45 x (1 + 7))
Total cost = $500 + ($45 x 8)
Total cost = $500 + $360
Total cost = $860
Therefore, the total cost of Sariah's payday loan is $860
