Question

a local city collects 8% sales tax if the total purchase was $216 then how much was collected for sales tax​

Answer 1

$17.28 was collected for sales tax

Explanation:

Step 1: Our output value is 216.

Step 2: We represent the unknown value with $x

Step 3: From step 1 above, $216 = 100%

Step 4: Similarly, $x = 8%

Step 5: This results in a pair of simple equations:

$216 = 100% (1)

$x = 8% (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have

216/x = 100%/8%

Step 7: Again, the reciprocal of both sides gives

x/216 = 8/100

⇒x=17.28​

Therefore, 8% of 216 is 17.28
