Answer 2

Answer:

Kelly bought 9 shirts.

Solution:

As given she spent total $\ 225$ on jeans and shirt

Let us assume that she bought x number of jeans and y number of shirts

She bought total 14 items,

Hence $x+y = 14$

$x=(14-y)$ ………… (i)

Each jens costs $\ 18$, So x number of jeans will cost total $\ 18x$

Each shirt costs $\ 15$, so y number of shirts will cost total $\ 15y$

So we can say ,

$18x +15y = 225$ ………… (ii)

Now substituting value of  (i) in (ii) we get,

$18\times(14-y) +15y = 225$

$252 -18y +15y = 225$

$-3y = 225 -252$

$-3y=-27$

$y = 9$

So, $x = (14-9) = 5$

She bought 9 shirts.
