The answer is b. 19.42. :)
The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:

× 9x
Write -6x as a difference.

× 9x
Factor out x from x² + 2x.

× 9x
Factor out -8 from -8(x + 2).

× 9x
Factor out x + 2 from the denominator (bottom) of the expression.

× 9x
Reduce the fraction with x + 2

× 9x
Finally,, calculate the product to find your final answer.

This means that the correct answer to your question is going to be option B.

Answer:
$11.47
Step-by-step explanation:
In order to calculate Mrs.Jackson's total we first need to turn the fractions into decimals by simply dividing the numerator by the denominators like so...
2/3 = 0.66
1 1/4 = 1.25
1/2 = 0.50
Now we need to multiply each products cost by the amount they bought in decimal form, then finally add them all together...
($0.51 * 0.66) + ($2 * 1.25) + ($4.50 * 0.50) + ($3.19 * 2) = x
0.34 + 2.5 + 2.25 + 6.38 = x
$11.47 = x
Finally, we can see that Mrs. Jackson's total was $11.47
