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

15% of Alina’s workout consisted of cardio exercise. 25% of Dane’s workout consisted of cardio exercise. Which statement must be
Arisa [49]


The correct answer is B. If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.

To figure this out, first find 15% of 80 and then 25% of 48.

To find 15% of 80, you can first find 10% of 80 which is 8(just move the decimal one place to the left). The remaining 5% will be half of 8 since 8 is 10%. Add both the numbers up and you will get 12. (8+4=12)

To find 25% of 48, you can divide 48 by 4. Since percent means 'out of 100', 25% is 25 of 100. 100 divided by 25 is equal to 4. So, 48 divided by 4 is equal to 12.

So, the final answer is B. They both equal to 12.

Hope it helps :)
