<span>z−7.8=32.9
add 7.8 to both sides
</span><span>z−7.8 + 7.8 = 32.9 + 7.8
simplify
z = 40.7</span>
Answer:
11 degrees.
Step-by-step explanation:
-2 + 13 = 11 Good luck man! :)
Firstly, you should find the discount that is taken off of the jacket, and then also find the sales tax.
As the discount is 10%, you simply have to divide 35 by 10. 35/10= 3.50.
Therefore, you need to subtract the 3.50 from the 35, which gives you 31.50. You've then got the 5% sales tax to add on, which is 3.50/2= 1.75, you've then got to add 1.75 to 31.50, which gives you 33.25.
However, if the sales tax is on the discounted price, then it will be 31.50/10= 3.15/2= 1.58, and you've then got to add this is to discount price, which is 31.50+1.58= 33.08
Hope this helps :)
