Answer:
16.67
Step-by-step explanation:
Step 1: We make the assumption that 20 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=20.
Step 4: In the same vein.
Step 5: This gives us a pair of simple equations
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
Step 7: Taking the inverse (or reciprocal) of both sides yields
