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.
20%
Here's a tip: Always start percentage calculating with dividing the current number by 10.
80%
Step-by-step explanation:
Votes: 24 were for hunger relief and 6 were for environmental causes. There were 24 + 6 = 30 votes in total.
Thus,
30 votes - 100%,
24 voyes - x%.
Mathematically, you can write a proportion:
I don’t know this question but you can’t divided by number and multiply
