Answer: the price of each CD before tax is $14.9
Step-by-step explanation:
Let x represent the price of each CD before tax.
Abdul bought 3 CDs that were each the same price. It means that the total cost of the 3 CDs before tax is $3x.
Including sales tax, he paid a total of $47.40. Of that total, $2.70 was tax. It means that
3x + 2.7 = 47.4
3x = 47.4 - 2.7
3x = 44.7
x = 44.7/3
x = 14.9
the price of each CD before tax is $14.9
Answer:
3/6
Step-by-step explanation:1/3 divided by 2/3 = 3/6
Start by converting your two equations into slope-intercept form.
3x - 3y = -9
-3y = -3x -9 Subtract 3x from both sides
y = x +3 Divide both sides by -3
2x + y = 9
y = -2x + 9 Subtract 2x from both sides.
Then graph both lines (in which case the point where they intersect is the solution) or substitute in each point until both equations are true.
In this case the solution is (2,5); both equations become 5=5 when you substitute in the point's coordinates.
The correct answer is B) y = 120000x + 420000.
We multiply 120,000 by x since that is the cost per person per day, and x is the number of days. We add 420,000 because that is the one time cost of the round trip airfare.
