The total cost of the meal including tip is $55.80.

Step-by-step explanation:

Cost of the meal = $46.50

tip = 20%

total cost = ?

Finding the tip cost:

20% of cost of the meal is equal to the tip cost.

20% of 46.50

(% = 1/100 and of means multiplication)

20/100 * 46.50

930/100

$9.30

20% tip = $9.30

Finding total cost:

Cost of the meal + tip

46.50 + 9.30

55.80

The total cost of the meal including tip is $55.80.
