Need Help on Math Question?

A store tripled the price it paid for a pair of jeans. After a month, the jeans were marked down $5. Two weeks later, the price was divided in half. Finally, the price was reduced by $3, and the jeans sold for $14.99

11) How much did the store pay for the jeans?

Answer 1

14.99+3=17.99

17.99x2=35.98

35.98+5=40.98

40.98/3=16.33

Answer 2

$40.98/3

=$13.66

Answer 3

Let x be the price the store paid for the jeans. Then we have the following equation:

(3x - 5)/2 - 3 = 14.99,

from which we get

3x = 17.99 x2 = 35.98

hence

x = 35.98/3 = 11,97 (approx).  

Answer 4

14.99=[3x-5] /2 - 3

***x= 13.66***

Answer 5

You can reverse the numbers and math.  Use addition instead of subtraction, and division instead of multiplication, and vice versa.

$14.99 + $3 x 2 + $5 / 3

$17.99 x 2 + $5 /3

$35.98 + $5 /3

$40.98 / 3 = $13.66

Just to prove it:

$13.66 x 3 = $40.98

$40.98 - $5 = $35.98

$35.98 / 2 = $17.99

$17.99 - $3 = $14.99
