At a restaurant you only have $20 to spend on dinner. In addition to the cost of the meal you must pay a 5% sales tax andleave a 15% tip. What is the most expensive item you can order?

$16.67

Step-by-step explanation:

alright so to do this you need some basic algebra

you have to pay an extra 20% of whatever you buy

thus we can make the following equation

.2x+x=20  (since 20 is the amount of money you have)

combining the like terms,

1.2x=20

and finally, dividing both sides by 1.2

x=$16.67

don't forget to check!

.05*16.67=.83 (sales tax makes the total $17.5)

.15*16.67=2.5 (tip makes the total $20)

whaddya you know, it works!

most expensive item you can buy will cost $16.67
