Answer:
b
Step-by-step explanation:
![\sqrt[3]{5 } \div \sqrt[4]{5}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B5%20%7D%20%20%5Cdiv%20%20%20%5Csqrt%5B4%5D%7B5%7D%20)
(5)^1/3 / (5)^1/4
base is same and powers are dividing so we will subtract powers
5^1/3-1/4
5^1/12
First you need to figure out the cost of the skateboard after the discount but before the sales tax. By doing 100%-12% you figure out how much of the original cost you are paying 88%. Then you multiply 79.99(original cost) and 88%(how much you pay) which gets you 70.39. Then you figure out the sales tax by multiplying 70.39 by 6.75% which gives you 4.75(the sales tax). And the last thing you need to do is add the cost before tax(70.39) and the tax(4.75).
The skateboard costs $75.14
