The town recreation department ordered a total of 100 baseballs and bats for the summer baseball camp. baseballs cost $4.50 each and balls cost $20 each. the total purchase was $822. how many of each item was ordered

76 baseballs and 24 bats.

Step-by-step explanation:

Total number of baseballs and bats = 100

Cost of baseball each = $4.50

Bats cost each = $20

Total cost = $822

This results in a simultaneous equation that can be solved by elimination or substitution method.

Let the number of baseballs purchased t

and the number of bats purchased be g

From the total numbers purchased,

t + g = 100

from g = 100 - t

From the total cost incurred

4.5t + 20g = 822

4.5t + 20(100 - t) = 822

4.5t + 2000 - 20t = 822

15.5t = 2000 - 822

15.5t = 1178

t = 1178/15.5

t = 76

But g = 100 - t

g = 100 - 76

g = 24

Therefore, the town recreation department ordered 76 baseballs and 24 bats.
