If 8% of c is equal to 12% of d, which of the following is equal to c+d?
3 answers
What following?
.08c = .12d
2c = 3d
so, c+d = 3/2 d+d = 5/2 d
or c + 2/3 c = 5/3 c
Not sure what your choices are...
2c = 3d
so, c+d = 3/2 d+d = 5/2 d
or c + 2/3 c = 5/3 c

to simplify .08c = .12d
multiply both sides by 100 to get
8c = 12d
Now divide both sides by 4 to get
2c = 3d
c = 3/2 d
c + d
3/2 d + 2/2 d = 5/2 d
multiply both sides by 100 to get
8c = 12d
Now divide both sides by 4 to get
2c = 3d
c = 3/2 d
c + d
3/2 d + 2/2 d = 5/2 d
