A-Substitute 3,200 for x.
B-Add 8 and 3,200.
C- Divide 3,192 by 168.
D-Isolate y in the equation.

Answer 1

The answer is C 
you substitute 3200 in for y
3200 = 168x +8
3192 = 168x
x=19

Answer 2

Answer:

Option C is the answer.

Step-by-step explanation:

A florist sale is for it's first month is represented by the equation y = 168x + 8

Here y represents the sales in dollars and x represents number of days.

Now we have to calculate the number of days it took to reach $3200 in sales.

For this we will substitute $3200 in place of y and find the value of x by solving the equation.

3200 = 168x + 8

168x = 3200 - 8 = 3192

$x=\frac{3192}{168}=19$

Therefore Option C. is the correct option.
