2 drinks: $2.30 each
a.
$65.82
b.
$65.10
c.
$54.85
d.

Answer 1

let's leave the tax calculations aside for a minute, and just look at the cost of the items

if he ordered 2 entries at 16.99 each, how much did he pay for the entries?

Answer 2

33.98

Answer 3

great!

he ordered 2 drinks at 2.30 each, how much did he pay for the drinks?

Answer 4

4.6

Answer 5

great!

so, he paid 4.60 for the drinks, 33.98 for the entries. he also bought 1 appetizer for 7.39 and 1 dessert for 5.29, how much did he pay for all these items?

Answer 6

51.26

Answer 7

good so far! however, we're not finished yet

he paid 51.26 for the items, but he also paid a 7% tax and a 20% gratuity

the 7% tax is equal to (0.07)*(cost of the items)

how much is the tax?

Answer 8

3.60 i rounded

Answer 9

good!

now, the 20% gratuity = (0.20)*(cost of the items)
what is the gratuity?

Answer 10

.71764

Answer 11

or do you do the orginal cost then multiply

Answer 12

10.30

Answer 13

oh, whoops, sorry, I forgot that gratuity gets calculated after tax...

so, let's add the cost of the items + tax

cost of the items = 51.26
tax = 3.60

let's add these together to get 54.86, with me so far?

Answer 14

yea

Answer 15

alright, gratuity = 0.20*(54.86) = 10.972

gratuity + total cost = 10.972 + 54.86 = $65.82 (rounded)

Answer 16

that should be our final answer, sorry for the confusion > >
