100 - 0.05 = 0.95
Expected monthly cost =
Monthly cost x 0.95 + office visit x 0.05
15 x 0.95 + 50 x 0.05
14.25 + 2.50 = $16.75
Yes 124 and 741 are relatively prime
Its $800 because to find interest u can use the formula I=PRT p is principal which is 500 times r which is rate-15/100(=15%) times 4
so the interest is 500×15/100×4=300
then u add 300 to 500 because the interest adds more money to the loan
