John took out a loan for 18,550. To pay it back he will make 60 monthly payments of 389. How much will he pay in interest?

He paid an of 4790

Step-by-step explanation:

If John took a loan of 18550

Then in 60 months, we will pay back 389 multiply by 60

389 × 60 = 23340

Therefore he paid an interest of 23340 minus 18550, that is

23340 - 18550 = 4790

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 -
