Yuto found a backpack on sale for 70 percent off. He used a coupon for an additional 10 percent off. If the original price of the backpack was $55, what is the final price of the backpack before taxes?

$11.00

Because  .70 + .10 = .80

.80 times 55 = 44

55 - 44 = 11

If you add tax however, it would be 11.66.

Because 11 times .06 = .66

.66 + 11 = 11.66

Step-by-step explanation:

mark me as brainliest pls :)

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✌✌✌
