The number of 11-inch softball is 70 and the number of 12-inch softball is 50.
Step-by-step explanation:
Given that,
- The cost of 11-inch softball = $2.50
- The cost of 12-inch softball = $3.50
Let us assume,
- The number of 11-inch softball be 'x'.
- The number of 12-inch softball be 'y'.
Forming the equation to solve x and y values :
- The total number of softball ordered = 120
- The total cost for 120 softballs = $350
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.
