Sales tax = $2.79
Step-by-step explanation:
(18 x 48.6)
/100
= 8.748 = $8.75 tip amount total
48.60-8.748 = 39.852 sales total
(39.852 x 7)/100
= 2.78964 = $2.79 sales tax
39.852 - 2.78964 = 37.06236 = $37.06 cost of bill
Sales tax was asked = $2.79
Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
