At Sam's birthday lunch, Sam and one of her friends each ordered a $4 salad while her other 4 friends each ordered a $6 sandwich

Brrunno [24]

Each person will pay $7 before taxes and tip.

Step-by-step explanation:

Price of salad = $4

Price of two salads = 4*2 =$8

Price of sandwich = $6

As 4 friends ordered sandwiches, therefore,

Price of 4 sandwiches = 6*4 = $24

Price of slice of cake = $3

Total = 2 salads + 4 sandwiches + 1 slice of cake

$Total = 8+24+3$

$Total = $35$

5 friends will split the bill evenly, therefore,

Bill for one person = $\frac{Total\ bill}{No.\ of\ people\ paying}$

Bill for one person = $\frac{35}{5} = \$7$

Each person will pay $7 before taxes and tip.
