Answer: a. The total cost of bananas and guavas purchased by Kiran is $12. The cost of bananas per pound is $1.50 and the cost of guavas per pound is $3.00. Thus, the equation relating the two variables can be written as:
1.5b + 3g = 12
where b is the number of pounds of bananas Kiran buys and g is the number of pounds of guavas he buys.
b. To rearrange the equation so b is the independent variable, we need to isolate b on one side of the equation. We can do this by first subtracting 3g from both sides of the equation:
1.5b = 12 - 3g
Then, we can divide both sides of the equation by 1.5:
b = 8 - 2g
Therefore, b is the independent variable and g is the dependent variable.
c. To rearrange the equation so g is the independent variable, we can follow a similar process. First, we can subtract 1.5b from both sides of the equation:
3g = 12 - 1.5b
Then, we can divide both sides of the equation by 3:
g = 4 - 0.5b
Therefore, g is the independent variable and b is the dependent variable.
