Using proportions, it is found that she will pay $8.28 in total after the discount.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Before tax, the total price is given by:
P = 3.59 + 4.25 + 3.99 = $11.83.
She gets a 30% discount, hence the proportion she pays is 70% of this amount, hence:
P = 0.7 x 11.83 = $8.28.
She will pay $8.28 in total after the discount.

Answer:
- <u><em>The cost of one rose bush is $ 9 and the cost on one bunch pf ornamental grass is $ 8.</em></u>
Explanation:
Name the variables and build a system of two equations with two unknowns.
<u>1. Variable r</u>: cost of one rose bush
<u>2. Variable g</u>: cost of one bunch of ornamental grass.
<u>3. First equation</u>:
- Shreya spent $68 on 4 rose bushes and 4 bunches of ornamental grass.
4r + 4g = 68
<u>4. Second equation</u>:
- Beth spent $115 on 11 rose bushes and 2 bunches of ornaments grass.
<u>5. System of equations</u>:
- 11r + 2g = 115 equation 2
<u>6. Solve the system</u>
a) Divide the equation 1 by 2:
- 11r + 2g = 115 equation 2
b) Subtract equation 1a from equation 2:
c) Substitute the value of r into the equation 1a:
<u>7. Conclusion</u>:
The cost of one rose bush is $ 9 and the cost on one bunch pf ornamental grass is $ 8.
