A softball coach has ordered softballs for two different leagues. The Junior League uses
dedylja [7]

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

<u>Step-by-step explanation</u>:

<u>Given that,</u>

  • The cost of 11-inch softball = $2.50
  • The cost of 12-inch softball = $3.50

<u>Let us assume,</u>

  • The number of 11-inch softball be 'x'.
  • The number of 12-inch softball be 'y'.

<u>Forming the equation to solve x and y values :</u>

  • The total number of softball ordered = 120
  • The total cost for 120 softballs = $350

x + y = 120  -------(1)

2.5x + 3.5y = 350   --------(2)

<u>Multiply eq(1) by 2.5 and subtract eq(2) from eq(1)</u>,

 2.5x +2.5y = 300

-<u>(2.5x +3.5y = 350)</u>

  <u>        -1y     =  -50</u>

Therefore the value of y = 50.

The number of 12-inch softball is 50.

<u>Substitute y=50 in eq(1),</u>

x+50 = 120

x = 120-50

x = 70

The number of 11-inch softball is 70.
