Sandy found 45 seashells on the beach, she gave Benny 17 of the seashells. How many seashells does she now have ? Please help asap. (:

45-17 = 28 thats the answer lol super easy

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
