Answer:
$17.28 was collected for sales tax
Step-by-step 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
