11. Cara has a loan from her credit union at a rate of 9.5% for which her payments are $185 per month. The interest is computed on a daily basis on the unpaid balance of the loan. If the load balance after her last payment was $2708 and Cara makes her next payment 30 days later, how much of the payment is paid toward interest?

A) $43.94             B) 21.14        C) $70.48             D) $7.05

Solution

9. Probability that Carl will beat his friend = 6/(6+5) = 6/11

10. possibilities = 1 + 6/1 + (6*5)/(2*1) + (6*5*4)/(3*2*1) + (6*5*4)/(3*2*1) + (6*5)/(2*1) + 6/1 + 1

= 1+ 6 + 15 + 20 + 20 + 15 + 6 + 1 = 88
