## Claire4christ 3 years ago Can someone help me with this please. A certain car costs $6,595 before taxes are added. Taxes are$460 and license tags cost $55. What is the overall tax rate (to the nearest tenth)? _____ % • This Question is Closed 1. ChristianGeek To calculate any percentage, divide the amount that is the percentage (the tax rate in this case) by the total and then multiply by 100. 2. ChristianGeek (In this case, the total would be the cost of the car.) 3. karatechopper Do i need to add the 55 to the carr amount? And then you want me to find tax? or tax amount with just car? 4. Claire4christ 6,595+460+55 do you add everything first ???? 5. Claire4christ im just so confused 6. ChristianGeek It's a confusing question the way it's phrased. When it says that the cost of the car is$6,595 before tax, that's your hint that $6,595 is the amount that will be taxed. The license tags are not taxed (the confusing part). So you have$460 tax on \$6,595. If we call the tax rate T (a percentage), the formula for the amount of tax is: $\frac{T}{100} \times 6595 = 460$ Let me know if you need help from there.

i think i need help

@ChristianGeek

9. Claire4christ

do you multiply 100 in both sides

10. ChristianGeek

np...let's take it to the next step by multiplying both sides by 100 to get rid of the fraction: $T \times 6595 = 460 \times 100$ Now we can divide both sides by 6595 to isolate T: $T = \frac{46000}{6595}$ Now you just need a calculator to finish up!

11. ChristianGeek

Yes (to multiplying by 100)...nice job!

12. Claire4christ

6.9

13. Claire4christ

is that right

14. ChristianGeek

Yes, except since the full fraction is 6.97... you would round up to 7.0

15. ChristianGeek

You can test your answer by plugging it back into the formula.

16. Claire4christ

they got answer 7.8 how

17. ChristianGeek

Give me a moment...

18. ChristianGeek

if all the numbers you gave are correct then there is no way they could have come up with 7.8!

19. ChristianGeek

(Unless license tags are considered tax.)

20. Claire4christ

maybe

21. Claire4christ

yes 55 is included

22. Claire4christ

i just did it thesame way and got 7.8 with 55 included

23. ChristianGeek

Yep, that's what they did. That is extremely confusing. Here's the math: $\frac{T}{100}\times6595 = 460 + 55$$\frac{T}{100}\times6595 = 515$$T\times6595 = 515 \times 100$$T = \frac{51500}{6595}$ Sorry about that. The problem is definitely not clear.

thank you

My pleasure.
