a) t = -7

b) f = 12

c) k = -13

Step-by-step explanation:

a) t + 11 = 4

t = -7

b) f = 8+4

f = 12

c) 5 = 18 + k

-13 = k

A= -7

B= 12

C= -13

Step-by-step explanation:

This is how I do it

A) Subtract 4 from each side, and when you do that you get 7=-t which makes the answer -7.

B) Add 8 to both sides and you get f=12.

C) Subtract 5 from each side, and when you do that you get -k=13 which makes the answer -13.

I hope this helps, and have a great day! :)

Also if you need more of an explanation I can help!

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
