Car Wash Fundraiser

Saturday| Number of cars washed
$1$|
$2$|
$3$|
$4$|
Key $1$ = $10$ cars

Answer 1

We first analyze the given pictograph and find the total number of cars washed each week and then multiply it with the amount charged for washing one car.

Complete step-by-step solution:
From the question stated as each Car symbol represents $10$ cars.
Since there are $3$ car symbols in the first Saturday, this means that:
For Saturday of the first week, total number of cars washed = $3 \times 10 = 30$ cars.
Since there are 2 car symbols in the first Saturday, this means that:
For Saturday of the second week, total number of cars washed = $2 \times 10 = 20$ cars.
Since there are 2 car symbols in the first Saturday, this means that:
For Saturday of the third week, total number of cars washed = $2 \times 10 = 20$ cars.
Since there are 5 car symbols in the first Saturday, this means that:
For Saturday of the fourth week, total number of cars washed = $5 \times 10 = 50$ cars.
Therefore, the total number of Cars washed would be the addition of the cars washed on all the Saturdays,
Therefore, Total cars washed in the entire month = $30 + 20 + 20 + 50 = 120$ cars.
Here in the question stated as the charge of washing $1$ car is equal to $5$
Therefore, Charge of washing $120$ cars = $5 \times 120 = 600$

$\therefore$The total amount raised by the football team is $600$.

Note: In this question we have another method as follows:
From the above pictograph we can see that the total numbers of car symbols are which $12$ is addition of the car symbols on all the Saturdays.
Now, we know that $1$ car symbol represents $10$ cars washed therefore; total number of cars washed is:
$10 \times 12 = 120$
Now we know the cost of washing 1 car is 5 therefore, the total amount of money raised by the team is:
$120 \times 5 = 600$
$\therefore$ The correct answer is $600$, which is raised by the Delhi school’s football team.
