Solve.Jack decided to put $600 into an IRA account every 3 months at a rate of 6% compounded quarterly. Find a recursive formula that represents his balance at the end of each quarter. How long will it be before the value of the account is $100,000? What will be the balance in 30 years when Jack retires?
A. B0 = 600 Bn = (1 + 
)B(n - 1) + 600; 21 years; $202,355
B. B0 = 600 Bn = (1 + 
)B(n - 1) + 600; 10 years; $6.8 million
C. B0 = 600 Bn = (1 + 
)B(n - 1) + 600; 7 years; $4 million
D. B0 = 600 Bn = (1 + 
)B(n - 1) + 600; 18 years; $151,860
Write an algebraic expression for the quantities being compared.The attendance on Monday was 22 people more than on Tuesday. The attendance on Wednesday was 14 people fewer than on Tuesday.
A. x = attendance on Monday x + 22 = attendance on Tuesday x - 14 = attendance on Wednesday B. x - 14 = attendance on Monday x = attendance on Tuesday x + 22 = attendance on Wednesday C. x + 22 = attendance on Monday x + 14 = attendance on Tuesday x = attendance on Wednesday D. x + 22 = attendance on Monday x = attendance on Tuesday x - 14 = attendance on Wednesday
