ANSWER ASAPA baseball team had $1,000 to spend on supplies. The team spent $185 on a new bat. New baseballs cost $4 each. The inequality 185 + 4b ≤ 1,000 can be used to determine the number of new baseballs (b) that the team can purchase. Which statement about the number of new baseballs that can be purchased is true? The team can purchase 204 new baseballs. The minimum number of new baseballs that can be purchased is 185. The maximum number of new baseballs that can be purchased is 185. The team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.
