Answer:
18x0.20 = 3.6 18-3.6 = 14.4
anwser- $14.40
Explanation:
18 is the original price of the shirt, and 20% is the discount. You can write the discount as 0.20 because it is the same as 20/100. To get the discount you have to multiply the original price and the discount, 18x0.20, 3.6. 3.6 is the discount price which means, it is not the final price because it only is 20% of 18. To check, multiply 3.6 by 5 becuse 100%= 1 and 5 times 0.2 equals to 100% (1). 3.6 x5 = 18. To get the final price, subtract 3.6 from 18 so the dicount can be added to the final price. Hope this helps :)
