Answer:
$70.34
Step-by-step explanation:
The total before the coupon and tax is:
$54.99 + $21.99 = $76.98
Now apply the 15% coupon:
Since the total price is 100% of the price, when you apply a 15% coupon, you pay 100% - 15% = 85% of the price. We need to find 85% of $76.98
85% * $76.98 =
= 0.85 * $76.98
= $65.43
The price after the 15% coupon, but before the tax, is $65.43
Now the total $65.43 is considered 100% of the price. The tax is 7.5%.
100% + 7.5% = 107.5%
Now we find 107.5% of $65.43
107.5% of $65.43 =
= 1.075 * $65.43
= $70.34
Answer: $70.34

Answer:
Option 1
Step-by-step explanation:
![\sqrt[4]{ {a}^{6} {b}^{4} {c}^{8} } \\ = {a}^{6 \div 4} {b}^{4 \div 4} {c}^{8 \div 4} \\ which \: gives \: option \: 1](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B%20%7Ba%7D%5E%7B6%7D%20%20%7Bb%7D%5E%7B4%7D%20%20%7Bc%7D%5E%7B8%7D%20%20%7D%20%5C%5C%20%20%20%3D%20%7Ba%7D%5E%7B6%20%20%5Cdiv%204%7D%20%20%7Bb%7D%5E%7B4%20%5Cdiv%204%7D%20%20%7Bc%7D%5E%7B8%20%5Cdiv%204%7D%20%5C%5C%20which%20%5C%3A%20gives%20%5C%3A%20option%20%5C%3A%201)
divide 2.49 by 5
2.49/5 = 0.498 rounded to nearest hundredth is 0.50 per pound
