Step-by-step explanation:
<h3> The complete exercise is: "Brown rice costs $2 per pound, and beans cost $1.60 per pound. Lin has $10 to spend on these items to make a large meal of beans and rice for a potluck dinner. Let b be the number of pounds of beans Lin buys and r be the number of pounds of rice she buys when she spends all her money on this meal.</h3><h3>1. Write an equation relating the two variables.</h3><h3>2. Rearrange the equation so "b" is the independent variable.</h3><h3>3. Rearrange the equation so "r" is the independent variable."</h3><h3 />
1. According to the information exercise given in the exercise, the cost per pounds of brown rice is $2. Since "r" represents the number of pounds of rice Lin buys, the total cost of the brown rice she buys can be represented with this expression:

The beans cost $1.60 per pound. Since "b" represents the number of pounds of beans Lin buys, the total cost of beans she buys can be represented as:

Knowing that she spends $10, you can write the following equation:

2. In order to rearrange the equation so "b" is the independent variable, you need to solve for "r":

3. To rearrange the equation so "r" is the independent variable, you must solve for "b". You get:

Y = mx
We just need to find the slope:
y2 - y1 / x2 -x1 = -4 - 4 / 1 - - 1 = -8/2 = -4/1 = -4
so: y = -4x
Hope that helps! :)
ANSWER

EXPLANATION
It was given that,a bottle of la belle bœuf contains 3/8 ounces of perfume.
We want to find how many ounces of perfume would 4 1/2 bottles contain.
If 1 bottle contains 3/8 ounces;
Then 4½ bottles should contain more ounces.
If more less divides.
4½ bottles contain


=1.6875 ounces.
