Shannonopens a savings account with $50. Each week after that she deposits $8 into her account. How many weeks does it take her to save $450

It will take 50 weeks for Shannon to have $450 on her account.

Step-by-step explanation:

Since we know that she already has $50 in her bank account we know that in order for her to have $450 she needs to put extra $400 (450 - 50 = 400). Now in order to find out how much weeks will it take we just need to divide the number of dollars that she still has to save by 8 (since she puts $8 each week), and so we get

400 / 8 = 50 weeks

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✌✌✌
