Answer:
I have ordered <u>30</u> softballs of 11-inch and <u>50</u> soft balls of 12-inch.
Step-by-step explanation:
Let the number of 11-inch softball be 'x'.
Let the number of 12-inch softball be 'y'.
Given:
Total number of soft balls = 80
Now we know that.
Total number of soft balls is equal to sum of the number of 11-inch softball and the number of 12-inch softball.
framing in equation form we get;
Also Given:
Price of 11- inch softball = $2.75
Price of 12-inch softball = $3.25
Total Bill = $245
Now we know that;
Total bill of soft balls is equal to sum of Price of 11- inch softball multiplied by the number of 11-inch softball and Price of 12- inch softball the number of 12-inch softball.
framing in equation form we get;
Now Multiplying equation 1 by 3.25 we get;
Now Subtracting equation 2 from equation 3 we get;
Dividing both side by 0.5 we get;
Now Substituting the value of 'x' in equation 1 we get;
Hence I have ordered <u>30</u> softballs of 11-inch and <u>50</u> soft balls of 12-inch.
