A car was sold 24 standard washed in a day , which was 25% of their total sales for that day . What was the total amount of wash
-Dominant- [34]

Answer:

96

Step-by-step explanation:

GIVEN: A car was sold 24 standard washed in a day , which was 25\% of their total sales for that day.

TO FIND: Total amount of washes that the car wash sold that day.

SOLUTION:

Let the total sales of car washes sold for that day =x

total number of standard car washes sold s=24

As, total standard car washes sold are 25\% of total sales in a day

s=\frac{25}{100}x

putting value in equation

24=\frac{25}{100}x

x=\frac{24}{25}\times100

x=96

Hence the total  number of car washes sold that day are 96
