Answer: The price for the meal after the coupon was used is : 28.80
Explanation:
A percentage is basically a fraction, with a denominator of 100, so:
10% = 10/100
15% = 15/100
Hence, 20% is 20/100
This fraction can be reduced to 1/5
Next multiply 36 by 1/5:
36 x 1/5 = 7.2
Another way to get the answer would be dividing by the reciprocal
36 divided by the reciprocal of 1/5 is 5/1, or just 5.
5 divided by 36 is 7.2
So, just add a zero to the end: 7. 20, that number is the amount that will be taken off.
Now we do the number that is taken off minus the amount of the meal:
7.20 - 36 = 28.80
The price for the meal after the coupon was used is : 28.80
Hope this helps! :)
