M5-9 estimating cost behavior using least-squares regression refer to the tan-o-rama data in m5-7. suppose sherri performed a least-squares regression and obtained the following results: page 227 put sherri’s results into a linear equation format (y = a + bx) and explain what each component means. compare the regression results to those obtained in m5-7 and m5-8. which method is most accurate? why? lo 5-5 m5-10 calculating unit contribution margin and contribution margin ratio refer to the tan-o-rama regression output given in m5-9. suppose that the company charges $6 per tanning session. calculate the unit contribution margin and contribution margin ratio as well as the total contribution margin if the shop books 400 tanning sessions this month.

Suppose that jim plans to borrow money for an education at texas a& m university. jim will need to borrow $25,000 at the end of each year for the next five years (total=$125,000). jim wishes his parents could pay for his education but they can’t. at least, he qualifies for government loans with a reduced interest rate while he is in school. he has a special arrangement with aggiebank to lend him the money at a subsidized rate of 1% over five years without having to make a payment until the end of the fifth year. however, at the end of the fifth year, jim agrees to pay off the loan by borrowing from longhorn bank. longhorn bank will lend him the money he needs at an annual interest rate of 6%. jim agrees to pay back the longhorn bank with 20 annual payments and the payments will be uniform (equal annual payments including principal and interest).
