Question:

After a storm damages the community center, Shanika and her friends hold fundraising events to help pay for repairs. After the first event, they raise $240, which is 10% of the total amount that they want to raise. What is the total amount of money that Shanika and her friends want to raise?

Answer:

The total amount of money that Shanika and her friends want to raise is $2400

Step-by-step explanation:

Here we have the amount raised = $240

Also we are told that the amount raised is only 10% of the amount they want to raise

Therefore if we put the amount they want to raise as D we have

10% of D = $240

That is;

\frac{10}{100} \times D = \$240

That means

D = \$240 \times  \frac{100}{10}  = 10 \times  \$240 = \$2400

Therefore, the total amount of money that Shanika and her friends want to raise = $2400.

GrogVix [38]

Answer:

"Jeromar" give away more tickets

Step-by-step explanation:

What we must do is calculate the amount to which a ticket is equivalent, to do this, the value of the purchase must be divided by the number of tickets they give away, as follows:

"Colima"

150/4 = 37.5

In other words, they give away 1 ticket for $ 37.50

"Jeromar"

100/3 = 33.33

In other words, they give away 1 ticket for $ 33.33

Which means that "Jeromar give away more tickets, because the cost of the ticket is lower
