Your restaurant bill comes to $46.27. Estimate a 10% tip.

The tip would be $4.63 unless you round it to $5

Step-by-step explanation:

10% of 46.27 is 4.627

Step-by-step explanation:

Step 1: Our output value is 46.27.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$46.27=100\%$.

Step 4: Similarly, $x=10\%$.

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

$46.27=100\%(1)$.

$x=10\%(2)$.

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

$\frac{46.27}{x}=\frac{100\%}{10\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{46.27}=\frac{10}{100}$

$\Rightarrow x=4.627$
