A softball coach has ordered softballs for two different leagues. The Junior League uses
an 11-inch softball priced at $2.50 each. The Senior League uses a 12-inch softball
priced at $3.50 each. The softball coach ordered a total of 120 softballs for $350.

The number of 11-inch softball is 70 and the number of 12-inch softball is 50.

Step-by-step explanation:

Given that,

Let us assume,

Forming the equation to solve x and y values :

x + y = 120  (1)

2.5x + 3.5y = 350   (2)

Multiply eq(1) by 2.5 and subtract eq(2) from eq(1),

 2.5x +2.5y = 300

-(2.5x +3.5y = 350)

         -1y     =  -50

Therefore the value of y = 50.

The number of 12-inch softball is 50.

Substitute y=50 in eq(1),

x+50 = 120

x = 120-50

x = 70

The number of 11-inch softball is 70.
