Answer:
y = 24
Step-by-step explanation:
3x + y = 6
Solve for y
Subtract 3x from each side
3x -3x+ y = 6-3x
y = 6-3x
Let x = -6
y = 6 -3(-6)
=6+18
=24
The ratio of wilma/teddy is 6/5 , if teddy has X then she has 21+X so you can solve X in this equation 6/5 = (21+x)/x
2.25 x 3 = 6.75
,6.75 x .05 = 0.34
,6.75 + 0.34 = 7.09
,Answer is $7.09
