Try this option:
1. if to re-write the given equation into the form -68x-34=qx-p and imagine it as two linear functions: y1=-68x-34 and y2=qx-p, then
2. according to the properties of linear function (y1||y2) q=-68 and p≠34. Note, if p=34, then y1≡y2.
answer: p=34; q=-68
Answer:
![\$16.625\approx \$16.30](https://tex.z-dn.net/?f=%5C%2416.625%5Capprox%20%5C%2416.30)
Step-by-step explanation:
Original price = $17.50
Discount = 5%
Find the amount of discount (in dollars):
![5\%=0.05\\ \\\$17.50\cdot 0.05=\$0.875](https://tex.z-dn.net/?f=5%5C%25%3D0.05%5C%5C%20%5C%5C%5C%2417.50%5Ccdot%200.05%3D%5C%240.875)
Now, the sale price is
![\text{Sale Price}=\text{Original Price}-\text{Discount}\\ \\\text{Sale Price}=\$17.50-\$0.875\\ \\\text{Sale Price}=\$16.625\approx \$16.30](https://tex.z-dn.net/?f=%5Ctext%7BSale%20Price%7D%3D%5Ctext%7BOriginal%20Price%7D-%5Ctext%7BDiscount%7D%5C%5C%20%5C%5C%5Ctext%7BSale%20Price%7D%3D%5C%2417.50-%5C%240.875%5C%5C%20%5C%5C%5Ctext%7BSale%20Price%7D%3D%5C%2416.625%5Capprox%20%5C%2416.30)
Answer:
Step-by-step explanation:
Cost price = (100/100+Profit%) * Selling Price = ( 100 /115)*40
= Rs. 34.78
Use a proportion.
2 adults to 18 students is as x adults to 99 students.
2/18 = x/99
18x = 2 * 99
18x = 198
x = 11
Answer: 11 adults
Answer:
