Answer:
25.19
Step-by-step explanation:
Change the percentage into a decimal. 30% is the same as saying 30/100.
This is 30 hundredths and in decimal form, it looks like this:
0.30 since 30/100 is the same as 3/10
To find out how much of a discount he gets, multiply 0.30 times 35.99.
0.30 x 35.99 = 10.797 which rounds up to 10.80.
This means he gets 10.80 off of the original price.
To find out what the new price is, subtract that from the original price.
35.99 - 10.80 = 25.19
