Bill and his friends went to red robin. Their order consisted of 2 hamburgers to $5.49 each, a chicken sandwich for $6.25, an order of ribs for $12.99, and 4 sodas at $ 1.75 each. They paid a 7% sales tax, and a 20% tip before tax. How much money did lunch cost them? show your work and explanation on how you solved it.

Lunch cost them $ 47.26

Step-by-step explanation:

We have the list of purchases they made as follows;

2 hamburgers = $5.49 + $5.49 = $ 10.98

1 chicken sandwich = $ 6.25

1 order of ribs = $ 12.99

4 soft drinks =$1.75 + $1.75 + $1.75 + $1.75=  $ 7

for a total of

$10.98 + $6.25 + $12.99 + $7 = $ 37.22

They paid a 20% tip for the value of the purchase that equals;

$37.22 * 0.20 = $7.44

taxes are also calculated according to the total purchase without including tips, as follows;

$37.22 * 0.7 = $2.60

then lunch cost them;

$37.22 + $7.44 + $2.60 = $ 47.26
