Cait purchases a $20 item at a store. She uses a coupon to receive a 15% discount and she pays 6% on the item. She calculates th

Sholpan [36]

A) Cait made two errors:

a discount is a deduction so it should be subtracted from the 100% (1.00 - 0.15 = 0.85), not added to 100% (1.00 + 0.15 = 1.15).
she paid 6% of the discounted amount, not 6% in addition to the discounted amount.

B) Original amount × Percent remaining after discount × percent paid

= (20)(0.85)(0.06)

= $1.02

PLEASE HELP ME!!!!!!!!!!!!!!!!!!

lilavasa [31]

Answer:

a) 4 - $vt - d = \frac{1}{2} at^{2}$

b) 1 - $2(vt - d) = at^{2}$

c) 6 - $\frac{2(vt - d)}{t^{2}} = a$

Step-by-step explanation:

It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.

We start with:

$d = vt - \frac{1}{2} at^{2}$

We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):

$vt - d = \frac{1}{2} at^{2}$

Then we multiply each side by 2 to get rid of the 1/2, answer #1:

$2(vt - d) = at^{2}$

Finally, we divide each side by t^2 to isolate a (answer #6):

$\frac{2(vt - d)}{t^{2}} = a$
