Answer 1

$7

Explanation:

You want to know the cost of each friend's meal if 5 friends spend $41 on their food, which includes a $6 delivery charge.

Cost

For 'a' friends spending 'x' on each meal, the total cost is ...

6 + ax = 41

Solving for x, we have ...

ax = 41 -6 = 35

x = 35/a

5 Friends

When the number of friends is a = 5, the cost of a meal is ...

x = 35/5 = 7

The cost of each friend's mean when the number of friends is 5 is $7.
