Dinner out at nice restaurant cost $45 plus a 20% tip what was the total cost of dinner ​

$54 because the tip would be $9 so just add 45 and 9

$54

Step-by-step explanation:

Since we are adding a 20% tip to the original cost of 45, the equation is

45+(0.2)(45),

since we want to add 20% of 45 to the original 45.

Solving that gives us 54.

step-by-step explanation:
