Answer:
buying price = $15,500
Step-by-step explanation:
selling price 20% more than the buying price
let the buying price be 100% then;
selling price = 120%
120% = $18,600
100% = ?
(100 × 18600) ÷ 120
= $15,500
Answer:
no
Step-by-step explanation:
Lets she how much money she has
1.00 dollars
5 * .25 = 1.25 quarters
4 * .10 = .40 dimes
7 * .01 = .07 pennies
Add it all together
1 + 1.25+ .40 +.07 =2.72
3.50 - 2.72 =.78
She is 78 cents short
Givens
x + y = 3
x =6 - 4y
Solution
Use the top equation to substitute for x in the second equation.
x = 3 - y
Put this result into the second given equation and solve for y
3 - y = 6 - 4y Add 4y to both sides.
3 - y + 4y = 6 Combine on the left
3 + 3y = 6 Subtract 3 from both sides
3 - 3 + 3y = 6 - 3 Combine
3y = 3 Divide by 3
3y/3 = 3/3 Combine
y = 1
=========================
x + y = 3 but y = 1
x + 1 = 3 Subtract 1 from both sides.
x + 1 - 1 =3 - 1
x = 2
Answer
x = 2
y = 1

I have only begun my Freshman Year of High School, and therefore I can only answer #2. Assuming they arrived at camp somewhere in the afternoon on the 188th day, take the amount of coffee and create a proportion for ounces of coffee/pound of coffee. Do this for all 27 pounds of coffee, because there are only three pounds left, and divide it by the amount of days the travel took. This method of solving will give you the answer.
