Answer:
21
Step by step explanation:
So, what we know is that we have 3 field goals, each worth 3 points, and 2 touchdowns, each worth 6 points. So we can do: 3 * 3 + 2 * 6. To break this down we first must do 3 * 3. This gets us an answer of 9, we then must do 2 * 6. Which gives us an answer of 12. Now that we have multiplied the 2, we may add, 9 + 12 = 21. Meaning our answer is 21. I hope this helped you out!

-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
