Answer:
Total after tax and discount is $7.78
Step-by-step explanation:
(10.49×0.3)= 3.15
10.49 - 3.15 = 7.34
(7.34×0.06)= 0.44
7.34 + 0.44 = 7.78
<u>Answer:</u>
The value in 3x + 2 = 15 for x using the change of base formula is 0.465 approximately and second option is correct one.
<u>Solution:</u>
Given, expression is 
We have to solve the above expression using change of base formula which is given as

Now, let us first apply logarithm for the given expression.
Then given expression turns into as, 
By using change of base formula,
x + 2 = 2.4649
x = 2.4649 – 2 = 0.4649
Hence, the value of x is 0.465 approximately and second option is correct one.
The answer is negative 1. This is because the sequence follows a pattern of the final number being 4, then 9, then 4 again. near the end of the sequence, you will end at the term of positive 4, which when 5 is subtracted from it (the pattern is -5), the first negative term is -1.
so 3 tenths is 0.3 and 5 tenths is 0.5 but if you need to add them you would get 0.8
