To find out how much Mrs. Blake will pay in total, including the tip, you need to calculate 18% of the bill amount and add it to the original bill.

First, calculate the tip amount:
18% of $42.75 = 0.18 * $42.75

To calculate this, multiply 0.18 by $42.75:
0.18 * $42.75 = $7.695

Rounding up to the nearest cent, the tip amount is $7.70.

Next, add the tip amount to the original bill:
$42.75 + $7.70 = $50.45.

Therefore, Mrs. Blake will pay a total of $50.45, including the tip.
