Answer:
187
Step-by-step explanation:
The company spends $649 on advertising
The sales function after advertising is given as:

When the total sales is $19,100, we have S(x) = 19100
So, the sales function becomes

Subtract 5 from both sides

Divide both sides by 7

Take exponents of both sides


Subtract 1 from both sides

Hence, the company spends $649 on advertising

Presuming the question is "Which sum is closest to 1".
First, you need to either convert all the fractions to decimals or all the decimals to fractions, then add each pair.
0.4 + 1/2 = 0.9
7/8 + 1/4 = 1.125
4/5 + 2/3 = 1.466666...
The first one is different from 1 by 0.1. The second is different by 0.125. The third is different by 0.46666.... Therefore, the closest sum is the first, or 0.4 + 1/2
0.4 + 1/2
<span>The answer to this question is Step 7.
Step 7 ⇒ −8 + 10 = x
− 10 + 10
This is where 10 is being added to both sides. It is not Step 4 as that uses the Subtraction Property of Equality (which can be proved true by taking the addition of a negative number).
