Answer:
A. 4.50 B. 1 : 3
Step-by-step explanation:
A.
First, think of Toby's money as 1/6x (x referring to the total amount of money) and Daoud's money as 1/2x.
It states that Toby gets 1.50, which means that 1/6x = 1.50.
To find what x is, multiply both sides by 6.
1/6x * 6 = 1.50 * 6
x = 9
Now that we know how much money there is in total, we can solve for Daoud's money. Daoud has 1/2x. We can substitute x for 9 and solve for Daoud's money.
1/2(9)
4.50
Daoud has 4.50.
B.
The problem states that Elsa gets the remaining money.
9 - (1.50 + 4.50)
9 - 6
3
Elsa gets 3.00.
Now, you can use turn solve the ratio of Toby's money and Elsa's money.
1.5 : 3
The problem states that they have to be whole numbers, so you can change the ratio to fit the requirements.
1 : 3
-6.125 is bigger because -6 1/5 is equal to -6.2 witch is smaller
(8x)^2 = 1
64 x^2 = 1
x^2 = 1/64
x = 1/8
Answer
The positive value of x that makes the equation true is x = 1/8
You would divide 32 into 3.52 for .11 per ounce.
You would divide 15 into 6.24 for .13 per ounce
So the better deal is the 32 ounces which is .02 per ounce cheaper.
