30 because it is yea and yea
Not exactly sure which equation you meant:
3(100-b)=6b
300-3b=6b
300=9b
b= about 33
100-3b=6b
100=9b
b=about 11
Answer:
x = 10
Step-by-step explanation:

or, 10x + 8 = 4(2x + 7)
or, 10x + 8 = 8x + 28
or, 10x - 8x = 28 -8
or, 2x = 20
or, x = 20/2
or, x = 10
x = 10
Answer:
new price= $2.40
Step-by-step explanation:
20%= 20/100= 1/5
$3.00/5= 00.60
1/5 of the price is being subtracted from $3.00
$00.60 is 1/5
3.00-.60= 2.40
