Eli took the fleet of 8 vans for oil changes. All of the vans needed windshield wipers which cost $24 per van. The total bill was $432. Write an equation to find out what each oil change cost. solve the equation.
We can define the cost of an oil change as x.
So, we have 8x.
There is also the added cost of $24 for each van's wipers.
This gives us 8x+24(8)=432 for the total cost.
Using the distributive property, this becomes 8x+192=432.
Afterwards, subtract 192.
8x=240
Divide by 8:
x=30
Each oil change therefore costed $30.
Thanks for your response
Let's assume the cost of each oil change is represented by variable "x".
Since Eli took 8 vans for oil changes and each van needed windshield wipers costing $24, the cost of windshield wipers for all the vans would be 8 * $24 = $192.
The total bill, including the cost of oil changes and windshield wipers, is $432.
Therefore, the equation to find out what each oil change cost is:
8x + $192 = $432.
To solve the equation, we need to isolate the variable "x". We can do this by subtracting $192 from both sides of the equation:
8x + $192 - $192 = $432 - $192
8x = $240
Now we divide both sides of the equation by 8 to solve for x:
(8x)/8 = $240/8
x = $30
So, each oil change costs $30.
To find out the cost of each oil change, let's assume the cost of each oil change as "x".
Since Eli took 8 vans for oil changes and all vans needed windshield wipers costing $24 per van, the total cost of the windshield wipers would be 8 * $24 = $192.
The total bill, including the cost of the windshield wipers, was $432. Therefore, the equation would be:
8x + $192 = $432
To solve the equation for x, we need to isolate the variable x on one side of the equation. Let's solve it step by step:
1. Subtract $192 from both sides of the equation to get rid of it:
8x = $432 - $192
8x = $240
2. Divide both sides of the equation by 8 to solve for x:
x = $240 / 8
x = $30
Therefore, each oil change cost $30.
