Answer:
$6x + $3 = $27
Amount of people in Jo's car: 4 People
Step-by-step explanation:
Let's set up the equation!
$6x + $3 = $27
We put = $27 because the problem states her total paid was $27 dollars.
We put $3 because she has to pay $3 for parking regardless how many people are in the car.
And lastly we put $6 because the 6 represents how the fee per person and the x represent how many people. We do not know how many people so we put a variable in place for now.
So let's solve this equation!
$6x + $3 = $27 (remember our goal is to isolate the variable to be alone!)
$6x +$3 -$3 = $27 - $3 (First! subtract 3 dollars from both sides) *lets solve*
$6x = $24 (Second! We solved $27 - $3 and cancelled out the 3 on the left side since $3 - $3 = $0
$6x = $24 (Third! We divide both sides by 6 to isolate x)
$6x/$6 = $24/$6 (Fourth! lets solve!)
x = 4 (The 6 is canceled out on the left side and we solved the right side.
Which leaves us with our answer, there are 4 people in the car.
Checking Answer Tip:
If you would like to check this answer, you can do that by plugging in 4 for the variable x. The answer would be correct if you get.
$27 = $27
Hope this helps! :)
