Answer:
$54.07
Step-by-step
Step 1: Our output value is 47.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 47 = 100%.
Step 4: Similarly, x=15%.
Step 5: This results in a pair of simple equations:
47 = 100% (1).
x = 15% (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
47/x = 100%/ 15%
Step 7: Again, the reciprocal of both sides gives
x/47 = 15/100
x=7.05.
Therefore, 15% of 47 is 7.04
47 + 7.04 = 54.07
(the / are fractions)
