Answer: I would go with C I hope i am right!!
Step-by-step explanation:
Answer:
6 crayons more
Step-by-step explanation:
At Dante's party, each child gets 192/16 = 12 crayons each
At Maria's party, each child gets 234/13 = 18 crayons each.
Therefore, each child at Maria's party gets 18-12 = 6 crayons more each than at Dante's party.
$2,500 • 7.5% (or 0.075) = $187.50 (for one year).
For two years, the interested added onto the original price is $375 because $187.50 • 2 (years) = $375.
$2,500 + $375 = $2,875
The total of the cost of the surgery and the interest is $2,875.
Hope this helps! ❤️
