Advanced Mathematical Decision ThinkingSemester 1 Pre-testPage 1229. You charged $658.17 on your new credit card for your college textbooks. Your credit card has an introductory APR of 6.8% for the first 6 months which gave you a monthly payment of $111.88. Assuming you managed to pay off the credit card in 6 months, how much of what you paid back was interest? A. $11.13
B. $671.28
C. $13.11
D. $680.86

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

no
