Noel's club wants to purchase 8 chairs for their meeting room. The original cost for each chair was $18.99. The chairs are now o

n sale for 10% off. How much will Noel's club save if they buy the 8 chairs on sale?
Which answer gives the correct solution and explains how to check if the answer is reasonable?

A.
Solution: $80

Explanation: If the club paid full price for the 8 chairs, they would pay about $20 for each chair. Since the chairs were 10% off, the club would pay $10 for each chair ($20 - $10).
That means they would save about 8 × $10 or $80.

B.
Solution: $15.20

Explanation: If the club paid full price for the 8 chairs, they would pay about $160 (8 × $20). Since the chairs were 10% off, that means the club would save about 0.10 × $160 or about $16.

C.
Solution: $71.92

Since the original price for each chair was about $19, the club would save about $9 per chair ($19 – $10). For all 8 chairs the club would save 8 × $9 or $72.

you take the 18.99 times it by .1 equals about 1.90 so you subtract that from 18.99 you get 17.09. Then multiply 17.09 by 8 and you get. 136.72. And that's how much you will be spending. So then you multiply 18.99 by 8 is 151.92. Subtract 136.72 by 151.92= 15.20 and the awnser is B

If you launch the cannonball from the ground instead (hi=0), what does that change in the original equation?
ikadub [295]

Answer:

  the value of hi changes from 58 to 0:

  h(t) = -4.9t^2 +19.8t

Step-by-step explanation:

If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.

  h(t)=-4.9t^2+19.8t+0\\\\\boxed{h(t)=-4.9t^2+19.8t}
