The total cost of a jacket and a pair of shoes was $95.11. If the price of the jacket was $2.79 less than the pair of shoes, wha
vovangra [49]

The <em>cost of the jacket</em> purchased using the <em>System of equation</em> is $46.16

<u>Given the cost prices</u> :

  • Total cost = $95.11
  • Cost of shoes = x
  • Cost of jacket = x - 2.79

<u>We could set up an equation relating the cost of each item to the total Cost : </u>

<em>Total cost = cost of jacket + cost of shoes</em>

95.11 = x - 2.79 + x

95.11 = 2x - 2.79

95.11 + 2.79 = 2x

97.90 = 2x

x = 97.90 / 2

x = 48.95

Cost of jacket = $48.95 - 2.79 = $46.16

Therefore, Cost of jacket is $46.16

If you have 720 pt/h how many qt/min is it
Maurinko [17]
So,

720 pt./hr.

2 pt. = 1 qt.

720/2 = 360

360 qt./hr.

Now, since there are 60 mins. in 1 hr., multiply the number by 60.

360(60) = 21600

720 pt./hr. = 21,600 qt./min.
