Question

Brianna has 64 seashells. She gives 1 fourth of her seashells to Maria. Next, she gives 10 seashells each to George and Ryan. Finally, she gives 75% of the seashells that remain to Dana. How many seashells does Brianna have left?

A) 27 seashells
B) 22 seashells
C) 15 seashells
D) 10 seashells

Answer 1

The amount of shells left would be 7

Using the parameters given ;

• Total number of shells = 64

Amount left after giving Maria :

• 64 - 1/4(64) = 48 shells

After giving George and Ryan :

• 48 - 10 - 10 = 28 shells

After giving Dana :

• 28 - 0.75(28) = 7

Therefore. Brianna will have 7 shells left
