HELP ME WITH MATH PLS!! Use one or more sets of brackets to calculate at least three different answers for this expression:
4.5 + 2 x 2.5-to-the-power-of 2 – 6 = ??

4.5 + (2 x 2.5 to the power of 2) - 6

4.5+12.5-6

17-6 = 11

(4.5+2) 2.5 to the power of 2 - 6

6.5 x 6.25 - 6

40.625 - 6 = 34.625

4.5 + 2(2.5 to the power of 2 - 6)

4.5 + 2 x 0.25

4.5+0.5+5

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
