If getting 20% off will save $180, what was the original price?

$900

Step-by-step explanation:

20% is 2/10 out of the original price. So divide $180 by 2 (90) and you will get the discount for 10%. If $90 is the discount for 10% off, then just do 90 times 10.

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✌✌✌
