$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)
