Question

Help please!!!!!!!!!!!!

Answer 1

Answer:

a=13.2

b=21

c=36

d=9

Step-by-step explanation:

a good way to do these is to find the simplest fraction, and multiply the number over 1 (a- 1/5*11/1 =11/5=2.2) then add the number to the total you have (a- 2.2+11=13.2) I have not done these questions in a while, so they may be off by a bit, or the formula may have a mistake, hope this helps anyway. :)

Answer 2

Answer:

Step-by-step explanation:

A x 20%=11

so a=11/.20

a=55

b x 75%=12

b=12/.75

B=16

c X 80%=20

c=20/.80

c=25

d x 200%=18

d=18/2

d=9
