Blake, Melissa, and Francisco went out for dinner. Blake's meal cost $15, Melissa's meal cost $12, and Francisco's meal cost $18. They also ordered a shared appetizer for $10. If they wanted to split the total bill evenly, how much should each person pay?

a
$13.75
b
$55.00
c
$18.33
d
$13

The total cost of the meals is $15 + $12 + $18 = $<<15+12+18=45>>45.

Including the cost of the shared appetizer, the total bill is $45 + $10 = $<<45+10=55>>55.
To split the bill evenly, each person should pay $55 ÷ 3 = $<<55/3=18.333333333333332>>18.33 (rounded to two decimal places).
Therefore, the answer is c) $18.33.
