Question 1143524
<br>
There are many ways to solve the problem using algebra.  Here is an outline of one of them (not necessarily the best).<br>
Let the number of cartons be x and the price of each carton be y.  Then<br>
{{{xy = 112}}}
{{{(x-2)(y+1) = 112}}}<br>
Since both expressions are equal to 112, set them equal to each other and simplify:<br>
{{{xy = (x-2)(y+1)}}}
{{{xy = xy+x-2y-2}}}
{{{x = 2y+2}}}<br>
Substitute that expression for x in the first equation:<br>
{{{(2y+2)y = 112}}}<br>
Solve for y and then use that value to determine the value of x.<br>
By far the easiest way to solve the problem is simply to play with numbers:<br>
112 = 16*7
112 = 14*8<br>
Those pairs of numbers satisfy the conditions of the problem:
16 cartons of eggs for $7 each;
14 cartons of eggs for $8 each
