If 15% of the total ticket sales is $375, what is the value of the total ticket sales?

Arisa [49]

Answer:

The value of the total ticket sales is, 2500

Step-by-step explanation:

Let x be the total ticket sales.

As per the statement:

if 15% of the total ticket sales is $375

$\text{15 \% of total ticket} = \frac{15}{100} \times x = \frac{15x}{100}$

then;

$\frac{15x}{100} = 375$

Divide both sides by 15 we have;

$\frac{x}{100} =25$

multiply both sides by 100 we have;

x = 2500

Therefore, the value of the total ticket sales is, 2500
