Amira's lunch bill was $14.50. She wants to leave a 20% tip for her waitress. Determine the total cost of her lunch bill.

Sagot :

In order to determine the total cost of Amiras's lunch, it is necessary to add to the initial cost of $14.50 the amount related to the tip of 20%.

Calculate the 20% of $14.50, by multiplying the factor 20/100 by 14.50:

[tex](\frac{20}{100})(14.50)=2.9[/tex]

20% of $14.50 is $2.9.

Hence, the total cost of the lunch was:

[tex]14.50+2.9=17.4[/tex]

$17.4
