Answer:

$43.2

Step-by-step explanation:

Given Formula : c=p(1+r)

r is in decimals

Where c is the final cost of the item

p is the price of the item before tax.

Now we are supposed to find the final cost of a $40 item after an 8% tax is applied

So, r = 8% = 0.08

p = $40

Substitute the values in the formula :

c=40(1+0.08)

So, c=43.2

Hence  the final cost of a $40 item after an 8% tax is applied is $43.2
