Answer:
Step-by-step explanation:
Step one:
given data
we are told that the cost of the meal is $45.50
the amount of the tip is 20% of the cost of the meal.
let 20% of $45.0 be x
Step two:
So, let us solve for 20% of $45.50
which is 20/100*45.50
x=0.2*45.5
x=9.1
This shows that the amount of the tip is $9.1
