3/4 w = 9
multiply by 4/3 on both sides
4/3 x 3/4 w = 9 x 4/3
w = 9 x 4/3
Simplify that
w = 3 x 4
w = 12
So your final answer is
multiply by 4/3 on both sides
4/3 x 3/4 w = 9 x 4/3
w = 9 x 4/3
Simplify that
w = 3 x 4
w = 12
So your final answer is
Answer:
The money left after gasoline expenses was <u>$622.50</u>.
Step-by-step explanation:
Given:
Last month, family had used 40% of the monthly income for gasoline, and 63% of that gasoline was consumed by the family's SUV.
The family's SUV used $261.45 worth of gasoline previous month.
Now, to find the money left of the family monthly income after gasoline expenses.
Let the total money spend on gasoline be
As, given:
The family's SUV used $261.45 worth of gasoline, which was 63% of the gasoline that was consumed.
According to question:
<em>Dividing both sides 0.63 we get:</em>
<u><em>The total money spend on gasoline = $415.</em></u>
Now, 40% of the monthly income is used for gasoline.
Let the total monthly income be
So, to get the monthly income we put an equation:
<em>Dividing both sides by 0.40 we get:</em>
<u><em>The total monthly income = $1037.50.</em></u>
Now, to get the money left after gasoline expenses we subtract the total money spend on gasoline from the total monthly income:
Therefore, the money left after gasoline expenses was $622.50.
