Dylan and Alyssa are going shopping to buy their friend a birthday gift. The item they are planning to buy has a regular price of $36, but is on sale at 20% discount. The store has a sales tax rate of 8 %. What will be the final price that Alyssa and Dylan will have to pay? Be sure to show your work to receive full credit.

$31.104

Step-by-step explanation:

Given :

Regular price = $36

Discount on sale = 20%

Discounted price = (100-20)%*36=0.8*36 = $28.8

Sales tax rate = 8% ;

Tax on sale = 8% * $28.8 = 2.304

Final amount that will have to be paid :

Discounted price + tax on sale

$28.8 + $2.304

= $31.104

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,
